Architectural Overview

Maxim’s Crimzon® ZLR16300 MCU is a ROM-based member of the Crimzon ZLR16300 family of general-purpose microcontrollers. With 1 KB to 16 KB of Program Memory and 237 B of general-purpose RAM, Maxim’s CMOS microcontrollers offer fast-executing, efficient use of memory, sophisticated interrupts, input/output (I/O) bit manipulation capabilities, automated pulse generation/reception, and internal key-scan pull-up transistors.
The Crimzon ZLR16300 architecture (see Figure 1 on page 3 and Figure 2 on page 4) is based on Maxim’s 8-bit microcontroller core with an Expanded Register File allowing access to register-mapped peripherals, I/O circuits, and powerful counter/timer circuitry. The Z8 structure, and a number of ancillary features that are useful in many consumer, automotive, computer peripheral, and battery-operated hand-held applications.

Features

There are three basic address spaces available to support a wide range of configurations:
1. Program Memory
2. Register File
3. Expanded Register File The Register file is composed of 256 B of RAM. It includes three I/O port registers, 16
control and status registers, and 237 general-pu rpose registers. The Expanded Register file consists of two additional register groups (F and D).
To unburden the program from coping with such real-time problems like generating complex waveforms or receiving and demodulating complex waveform/pulses, the Crimzon ZLR16300 offers a new intelligent counter/timer architecture with 8-bit and 16-bit counter/timers (see Figure 2 on page 4). Also included are a large number of user-selectable modes and two on-board comparators to process analog signals with separate reference voltages.
Table 1 lists the features of Crimzon ZLR16300 family.

Pin Functions

Caution:
XTAL1 Crystal 1 (Time-Based Input)
This pin connects a parallel-resonant crystal or ceramic resonator to the on-chip oscillator input. Additionally, an external single-phase clock can be connected to the on-chip oscillator input.
XTAL2 Crystal 2 (Time-Based Output)
This pin connects a parallel-resonant crystal or ceramic resonant to the on-chip oscillator output.
Input/Output Ports
Crimzon® ZLR16300
Product Specification
7
The CMOS input buffer for each ports 0, 1, or 2 pin is always connected to the pin, even when the pin is configured as an output. If the pin is configured as an open-drain output and no external signal is applied, a High output state causes the CMOS input buffer to float. This leads to excessive leakage current o f more than 10 0 A. T o pr event this leakage, connect the pin to an external signal with a defined logic level or ensure its output state is Low, especially during STOP mode.
Internal pull-ups are disabled on any given pin or group of port pins when programmed into output mode.
Port 0, 1, and 2 have both input and output capability. The input logic is always present no matter whether the port is configured as input or output. While performing a READ instruction, the MCU reads the actual value at the input logic but not from the output buffer. In addition, the instructions of OR, AND, and XOR have the Read-Modify-Write sequence. The MCU first reads the port, modifies the value, and loads back to the port.
Precaution must be taken if the port is configured as open-drain output or if the port is driving any circuit that makes the voltage different from the desired output logic. For example, pins P00–P07 are not connected to anything else. If it is configured as open­drain output with output logic as ONE, it is a floating port and reads back as ZERO. The following instruction sets P00-P07 all Low.

Port 0 (P07–P00)
Port 0 is an 8-bit, bidirectional, and CMOS-compatible port. These eight I/O lines ar e con­figured under software control as a nibble I/O port. The output drivers are push-pull or open-drain controlled by bit D2 in the PCON register.
If one or both nibbles are required for I/O operation, they must be configured by writing to the Port 0 mode register. After a hardware reset, Port 0 is configured (see Figure 5) as an input port.
An optional pull-up transistor is available as a mask option on all Port 0 bits with nibble select.
The Port 0 direction is reset to be input following an Stop Mode Recovery.

Port 2 is an 8-bit, bidirectional, and CMOS-compatible I/O port (see Figure 6). These eight I/O lines are independently configured under software control as inputs or outputs. Port 2 is always available for I/O operation. A mask option connects eight pull-up transistors on this port. Bits programmed as outputs are globally programmed as either push-pull or open-drain. The POR resets with the eight bits of Port 2 configured as inputs.
Port 2 also has an 8-bit input OR and AND gate which can be used to wake up the part. P20 is programmed to access the edge-detection circuitry in DEMODULATION mode.

Two on-board comparators process analog signals on P31 and P32, with reference to the voltage on Pref1 and P33. The analog function is enabled by programming the Port 3 Mode Register (bit 1). P31 and P32 are programmable as rising, falling, or both edge triggered interrupts (IRQ register bits 6 and 7). Pref1 and P33 are the comparator reference voltage inputs. Access to the Counter Timer edge-detection circuit is through P31 or P20 (see T8 and T16 Common Functions—CTR1(0D)01h on page 23). Other edge detect and IRQ modes are described in Table 5.
Comparators are powered down by entering STOP mode. For P31–P33 to be used in a SMR source, these inputs must be placed into DIGITAL mode.

Comparator Inputs
In ANALOG mode, P31 and P32 have a comparator front end. The comparator reference is supplied to P33 and P
. In this mode, the P33 internal data latch and its
REF1
corresponding IRQ1 are diverted to the SMR sources (excluding P31, P32, and P33) as displayed in Figure 7 on page 10. In DIGITAL mode, P33 is used as D3 of the Port 3 input register, which then generates IRQ1.
Comparators are powered down by entering STOP mode. For P31–P33 to be used in a Stop Mode Recovery source, these inputs must be placed into DIGITAL mode.
Comparator Outputs
These channels are programmed to be output on P34 and P37 through the PCON register.

Expanded Register File

Note:
The register file has been expanded to allow for additional system control registers and for mapping additional peripheral devices into the register address area. The Z8 register address space (0 through15 (OFh)) has been implemented as 16 banks, with 16 registers per bank. These register banks are known as the ERF (Expanded Register File). Bits 7–4 of register RP select the working register group. Bits 3–0 of register RP select the expanded register file bank.
An expanded register bank is also referr ed to as an expanded r egister gr oup (see Figure 10 on page 17).

Register File

The Register file (bank 0) consists of three I/O port registers, 237 general-purpose regis­ters, 16 control and status registers (R0, R2, R3, R4–R239, and R2 40–R255, respectively), and two expanded register Banks D (see Table 6 on page 22) and F . Instructions can access registers directly or indirectly through an 8-bit address field, thereby allowing a short, 4­bit register address to use the Register Pointer (see Figure 12 on page 20). In the 4-bit mode, the register file is divided into 16 working register groups, each occupying 16 con­tinuous locations. The Register Pointer addresses the starting location of the active work­ing register group.
Register address E0h–EFh can be accessed only through working registers and indirect addressing modes.

T8 Enable
This field enables T8 when set to 1.
Single/Modulo-N
When set to 0 (MODULO-N), the counter reloads the initial value when the terminal count is reached. When set to 1 (Single-Pass), the counter stops when the terminal count is reached.
Timeout
This bit is set when T8 times out (terminal count reached). T o r eset this bit, write a 1 to its location.
Writing a 1 is the only way to reset the Terminal Count status condition. Reset this bit before using/enabling the counter/timers.
23
The first clock of T8 might not have complete clock width and can occur any time when enabled.
Ensure to manipulate CTR0, bit 5 and CTR1, bits 0 and 1 (DEMODULATION mode) while using the OR or AND commands. These instructions use a Read-Modify-Write sequence in which the current status from the CTR0 and CTR1 registers is ORed or ANDed with the designated value and then written back into the registers.
T8 Clock
These bits define the frequency of the input signal to T8.
Capture_INT_Mask
Set this bit to allow an interrupt when data is captured into either LO8 or HI8 upon a posi­tive or negative edge detection in CAPTURE Mode.
Counter_INT_Mask
Set this bit to allow an interrupt when T8 has a timeout.
P34_Out
This bit defines whether P34 is used as a normal output pin or the T8 output.

If the result is 0, the counter/timers are in TRANSMIT mode, else, they are in DEMODU­LATION mode.
P36_Out/Demodulator_Input
In TRANSMIT mode, this bit defines whether P36 is used as a normal output pin or the combined output of T8 and T16.
In DEMODULATION mode, this bit defines whether the input signal to the Counter/Tim­ers is from P20 or P31.
If the input signal is from Port 31, a capture event generates an IRQ2 interrupt. To prevent generating an IRQ2, either disable the IRQ2 interrupt by clearing its IMR bit D2 or use P20 as the input.
T8/T16_Logic/Edge_Detect
In TRANSMIT mode, this field defines how the outputs of T8 and T16 are combined (AND, OR, NOR, NAND).
In DEMODULATION mode, this field defines which edge is detected by the edge detec­tor.
Transmit_Submode/Glitch Filter
In TRANSMIT mode, this field defines whether T8 and T16 are in the PING-PONG mode or in independent Normal operation mode. Setting this field to ‘Normal Operation mode’ terminates the ‘PING-PONG mode’ operation. When set to 10, T16 is immediately forced to a 0; a setting of 11 forces T16 to output a 1.
In DEMODULATION mode, this field defines the width of the glitch that must be filtered out.

Crimzon® ZLR16300
Note:
Product Specification
Initial_T8_Out/Rising_Edge
In TRANSMIT mode, if 0, the output of T8 is set to 0 when it starts to count. If 1, the out­put of T8 is set to 1 when it starts to count. When the counter is not enabled and this bit is set to 1 or 0, T8_OUT is set to the opposite state of this bit. This ensures that when the clock is enabled, a transition occurs to the initial state set by CTR1, D1.
In DEMODULATION mode, this bit is set to 1 when a rising edge is detected in the input signal. In order to reset the mode, a 1 should be written to this location.
Initial_T16 Out/Falling _Edge
In TRANSMIT mode, if it is 0, the output of T16 is set to 0 when it starts to count. If it is 1, the output of T16 is set to 1 when it starts to count. This bit is effective only in NOR­MAL or PING-PONG mode (CTR1, D3; D2). When the counter is not enabled and this bit is set, T16_OUT is set to the opposite state of this bit. This ensures that when the clock is enabled, a transition occurs to the initial state set by CTR1, D0.
26
In DEMODULATION mode, this bit is set to 1 when a falling edge is detected in the input signal. In order to reset it, a 1 should be written to this location.
Modifying CTR1 (D1 or D0) while the counters are enabled causes unpredictable output from T8/16_OUT.

Input Circuit

The edge detector monitors the input signal on P31 or P20. Based on CTR1 D5–D4, a pulse is generated at the Pos Edge or Neg Edge line when an edge is detected. Glitches in the input signal that have a width less than specified (CTR1 D3, D2) are filtered out (see
Figure 13).

Product Specification
When T8 is enabled, the output T8_OUT switches to the initial value (CTR1, D1). If the initial value (CTR1, D1) is 0, TC8L is loaded, else, TC8H is loaded into the counter. In SINGLE-PASS mode (CTR0, D6), T8 counts down to 0 and stops, T8_OUT toggles, the timeout status bit (CTR0, D5) is set, and a timeout interrupt can be generated if it is enabled (CTR0, D1). In MODULO-N mode, upon reaching terminal count, T8_OUT is toggled, but no interrupt is generated. From that point, T8 loads a new count (if the T8_OUT level now is 0), TC8L is loaded; if it is 1, TC8H is loaded. T8 counts down to 0, toggles T8_OUT, and sets the timeout status bit (CTR0, D5), thereby generating an inter­rupt if enabled (CTR0, D1). One cycle is complete. T8 then loads from TC8H or TC8L according to the T8_OUT level and repeats the cycle. See Figure 15.

Product Specification
Using the same instructions for stopping the counter/timers and setting the status bits is not recommended.
Two successive commands are necessary. First, the counter/timers must be stopped. Sec­ond, the status bits must be reset. These commands are required because it takes one coun­ter/timer clock interval for the initiated event to actually occur. See Figure 16 and
Figure 17.

When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected during counting, the current value of T8 is complemented and put into one of the capture registers. If it is a positive edge, data is put into LO8; if it is a negative edge, data is stored in HI8. From that point, one of the edge detect status bits (CTR1, D1; D0) is set, and an interrupt is generated if enabled (CTR0, D2). Meanwhile, T8 is loaded with counting again.

In NORMAL or PING-PONG mode, the output of T16 when not enabled, is dependent on CTR1, D0. If it is a 0, T16_OUT is a 1; if it is a 1, T16_OUT is 0. You can force the output of T16 to either a 0 or 1 whether it is enabled or not by programming CTR1 D3; D2 to a 10 or 11.
When T16 is enabled, TC16H * 256 + TC16L is loaded, and T16_OUT is switched to its initial value (CTR1, D0). When T16 counts down to 0, T16_OUT is toggled (in NOR­MAL or PING-PONG mode), an interrupt (CTR2, D1) is generated (if enabled), and a sta­tus bit (CTR2, D5) is set. See Figure 20.

Figure 20. 16-Bit Counter/Timer Circuits
Global interrupts override this function as described in Interrupts on page 39.
If T16 is in SINGLE-PASS mode, it is stopped at this point (see Figure 21 on page 36). If it is in MODULO-N mode, it is loaded with TC16H * 256 + TC16L, and the counting continues (see Figure 22 on page 36).
19-4622; Rev 0; 5/09 Functional Description
The values in TC16H and TC16L can be modified at any time. The new values take effect when they are loaded.

T16 DEMODULATION Mode
You must program TC16L and TC16H to FFh. Once T16 is enabled, and the first edge (rising, falling, or both depending on CTR1 D5; D4) is detected, T16 captures HI16 and LO16, reloads, and begins counting.
If D6 of CTR2 Is 0
When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected during counting, the current count in T16 is complemented and put into HI16 and LO16. When data is captured, one of the edge detect status bits (CTR1, D1; D0) is set, and an interrupt is generated if enabled (CTR2, D2). T16 is loaded with
This T16 mode is generally used to measure space time, the length of time between bursts of carrier signal (marks).

Product Specification
If D6 of CTR2 Is 1
T16 ignores the subsequent edges in the input signal and continues counting down. A timeout of T8 causes T16 to capture its current value and generate an interrupt if enabled (CTR2, D2). In this case, T16 does not reload and continues counting. If the D6 bit of CTR2 is toggled (by writing a 0 then a 1 to it), T16 captures and reloads on the next edge (rising, falling, or both depending on CTR1, D5; D4), continuing to ignore subsequent edges.
This T16 mode generally measures mark time, the length of an active carrier signal burst.
37
If T16 reaches 0, T16 continues counting from
FFFFh. Meanwhile, a status bit (CTR2 D5)
is set, and an interrupt timeout is generated if enabled (CTR2 D1).
PING-PONG Mode
This operation mode is valid only in TRANSMIT mode. T8 and T16 must be programmed in SINGLE-PASS mode (CTR0, D6; CTR2 , D6), and Ping-Pong mode must be pro­grammed in CTR1, D3; D2. You can begin the operation by enabling either T8 or T16 (CTR0, D7 or CTR2, D7). For example, if T8 is enabled, T8_OUT is set to this initial value (CTR1, D1). According to T8_OUT's level, TC8H or TC8L is loaded into T8. After the terminal count is reached, T8 is disabled, and T16 is enabled. T16_OUT then switches to its initial value (CTR1, D0), data from TC16H and TC16L is loaded, and T16 starts to count. After T16 reaches the terminal count, it stops, T8 is enabled again, repeating the entire cycle. Interrupts are allowed when T8 or T16 reaches terminal control (CTR0, D1; CTR2, D1). To stop the Ping-Pong operation, write 00 to bits D3 and D2 of CTR1. See
Figure 23.
Enabling Ping-Pong operation while the counter/timers are running might cause intermit­tent counter/timer function. Disable the counter/timers and reset the status Flags before instituting this operation.

Initiating PING-PONG Mode
Ensure that both counter/timers are not running. Set T8 into SINGLE-PASS mode (CTR0, D6), set T16 into SINGLE-PASS mode (CTR2, D6), and set the PING-PONG mode (CTR1, D2; D3). These instructions can be in random order. Finally, start PING-PONG mode by enabling either T8 (CTR0, D7) or T16 (CTR2, D7). See Figure 23 on page 38.
38
Figure 24. Output Circuit
The initial value of T8 or T16 must not be
1. If you stop the timer and restart the timer,
reload the initial value to avoid an unknown previous value.
During PING-PONG Mode
The enable bits of T8 and T16 (CTR0, D7; CTR2, D7) are set and cleared alternately by hardware. The timeout bits (CTR0, D5; CTR2, D5) are set every time the counter/timers reach the terminal count.
Timer Output
The output logic for the timers is displayed in Figure 24. P34 is used to output T8-OUT when D0 of CTR0 is set. P35 is used to output the value of T16-OUT when D0 of CRTR2 is set. When D6 of CTR1 is set, P36 outputs the logic combination of T8-OUT and T16­OUT determined by D5 and D4 of CTR1.

Interrupts

Crimzon® ZLR16300
Product Specification
The Crimzon ZLR16300 features six different interrupts (see Table 10 on page 41). The interrupts are maskable and prioritized (see Figure 25 on page 40). The six sources are divided as follows:
Three sources are claimed by Port 3 lines P33–P31
Two by the counter/timers (see Table 10 on pag e 41)
One for low-voltage detection
The Interrupt Mask Register (globally or individually) enables or disables the six interrupt requests.
The source for IRQ is determined by bit 1 of the Port 3 mode register (P3M). When in DIGITAL mo de, Pin P33 is the source. When in ANALOG mode the output of the Stop Mode Recovery source logic is used as the source for the interrupt. See Figure 30 on page
47.

When more than one interrupt is pending, priorities are resolved by a programmable prior­ity encoder controlled by the Interrupt Priority Register. An interrupt machine cycle acti­vates when an interrupt request is granted. As a result, all subsequent interrupts are disabled, and the Program Counter and Status Flags are saved. The cycle then branches to the Program Memory vector location reserved for that interrupt. All Crimzon ZLR16300 interrupts are vectored through locations in the Program Memory. This memory location and the next byte contain the 16-bit address of the interrupt service routine for that partic­ular interrupt request. To accommodate polled interrupt systems, interrupt inputs are masked, and the Interrupt Request register is polled to determine which of the interrupt requests require service.
An interrupt resulting from AN1 is mapped into IRQ2, and an interrupt from AN2 is mapped into IRQ0. Interrupts IRQ2 and IRQ0 can be rising, falling, or both edge trig­gered. You can program these interrupts. The software can poll to identify the state of the pin.
Programming bits for the Interrupt Edge Select are located in the IRQ Register (R250), bits D7 and D6. Table 11 indicates the IRQ configuration.

The device’ s on-ch ip oscill ato r has a high-gai n, parallel-resonant amplifier for connection to a crystal, ceramic resonator, or any suitable external clock source (XTAL1 = Input, XT AL2 = Output). The crystal must be AT cut, 1 MHz to 8 MHz (maximum) with a series resistance (RS) less than or equal to 100 . The on-chip oscillator is driven with a suitable external clock source.
The crystal must be connected across XTAL1 and XTAL2 using the recommended capac­itors from each pin to ground. The typical capacitor value is 10 pF for 8 MHz.
Check with the crystal supplier for the optimum capacitance.
Figure 26. Oscillator Configuration
Maxim’s IR MCU supports crystal, resonator, and oscillator. Most resonators have a fre­quency tolerance of less than ±0.5%, which is enough for remote control application. Res­onator has a very fast startup time, which is around few hundred microseconds. Most crystals have a frequency tolerance of less than 50 ppm (±0.005%). However, crystal needs longer startup time than the resonator. The large loading capacitance slows down the oscillation startup time. Maxim suggests not to use more than 10 pF loading capacitor for the crystal. If the stray capacitance of the PCB or the crystal is high, the loading capac­itance C1 and C2 must be reduced further to ensure stable oscillation before the T (Power-On Reset time is typically 5–6 ms, see Table 18 on page 75).
POR
For SMR operation, bit 5 of SMR register allows you to select the SMR delay, which is the

wakes up from the STOP mode. If resonator or crystal is used as a clock source then SMR delay needs to be selected (bit 5 of SMR = 1).
19-4622; Rev 0; 5/09 Functional Description
For both resonator and crystal oscillator, the oscillation ground must go directly to the ground pin of the microcontroller. The oscillation ground must use the shortest distance from the microcontroller ground pin and it must be isolated from other connections.

Power Management

Power-On Reset

A timer circuit clocked by a dedicated on-board RC-oscillator is used for the Power-On Reset timer function. The POR time allows V before instruction execution begins.
The POR timer circuit is a one-shot timer triggered by one of three conditions:

Standby.

2. Stop Mode Recovery (if D5 of SMR = 1).
3. WDT Timeout. The POR timer is 2.5 ms minimum. Bit 5 of the Stop-Mode Register determines whether
the POR timer is bypassed after Stop Mode Recovery (typical for external clock).
HALT Mode
This instruction turns Off the internal CPU clock, but not the XTAL oscillation. The coun­ter/timers and external interrupts IRQ0, IRQ1, IRQ2, IRQ3, IRQ4, and IRQ5 remain active. The devices are recovered by interrupts, either externally or internally generated. An interrupt request must be executed (enabled) to exit HALT mode. After the interrupt service routine, the program continues from the instruction after the HALT.
STOP Mode
This instruction turns OFF the internal clock and external crystal oscillation, reducing the standby current to 10 A or less. STOP mode is terminated only by a reset, such as WDT timeout, POR or SMR. This condition causes the processor to restart the application pro­gram at address
000Ch. In order to enter STOP (or HALT) mode, first flush the instruction
pipeline to avoid suspending execution in mid-instruction. Execute an NOP instruction (Opcode =
FFh) immediately before the appropriate sleep instruction, as follows:
FF NOP ; clear the pipeline 6F STOP ; enter Stop Mode
or
FF NOP ; clear the pipeline 7F HALT ; enter Halt Mode

Watchdog Timer Mode

Watchdog Timer Mode Register (WDTMR)
The W atchdog T imer is a retriggerable one-shot timer that resets the Z8 if it reaches its ter­minal count. The WDT must initially be enabled by executing the WDT instruction. On subsequent executions of the WDT instruction, the WDT is refreshed. The WDT circuit is driven by an on-board RC-oscillator. The WDT instruction affects the Zero (Z), Sign (S), and Overflow (V) Flags.
The POR clock source the internal RC-oscillator . Bits 0 and 1 of the WDT register control a tap circuit that determines the minimum timeout period. Bit 2 determines whether the WDT is active during HALT, and Bit 3 determines WDT activity during ST OP. Bits 4 through 7 are reserved (see Figure 32). This register is accessible only during the first 60 processor cycles (120 XTAL clocks) from the execution of the first instruction after Power-On Reset, Watchdog Reset, or a Stop Mode Recovery (see Figure 31 on page 49). After this point, the register cannot be modified by any means (intentional or otherwise). The WDTMR cannot be read.

Voltage Detection and Flags
The Voltage Detection register (LVD, register 0Ch at the expanded register bank 0Dh) offers an option of monitoring the V 0 of LVD register is set. When V oltage Detection is enabled, the V

real time. The Flags in the LVD register valid 20 us after Voltage Detection is enabled. The HVD Flag (bit 2 of the L VD register) is set only if V
is lower than the V
CC
HVD
. When Voltage Detection is enabled, the LVD Flag also triggers IRQ5. The IRQ bit 5 latches the low-voltage condition until it is cleared by instructions or reset. The IRQ5 interrupt is served if it is enabled in the IMR register. Otherwise, bit 5 of IRQ register is latched as a Flag only.
If it is necessary to receive an L VD interrupt upon power -up at an operating voltage lower than the low battery detect threshold, enable interrupts using the Enable Interrupt instruc­tion (EI) prior to enabling the voltage detection.
