•Be sure to evaluate your system with an evaluation MCU. Before starting mask production, evaluate your system and make final confirmation with a CS (Commercial Sample) version MCU.

Notes on Power Supply to the Target System:

•Pin Vcc of the emulator is connected to the target system to observe the voltage of the target system. Therefore design your system so that the target system is powered by an external power supply.

•The voltage of the target system should be within the MCU's specified range.

•Do not change the voltage of the target system after turning on the power.

( 12 / 84 )

IMPORTANT

Note on Clock Supply to the MCU:

•Clock can be supplied to the evaluation MCU in one of the following two ways. This is determined by emulator debugger clock selection.

(1)When Internal is selected:

A clock generated by the oscillation circuit in the emulation pod is supplied to the evaluation MCU. The clock is continually supplied to the evaluation MCU regardless of "target system clock status" and "user program execution status".

(2)When External is selected:

Clock supply to the evaluation MCU depends on oscillation status (oscillate/off) of the target system.

Note on RESET* Input:

•"L" input from the target system to pin RESET* is accepted only while a user program is being executed (only while the RUN status LED on the PC4701's front panel is lit).

Note on NMI* Input:

•"L" input from the target system to pin NMI* is accepted only while a user program is being executed (only while the RUN status LED on the PC4701's front panel is lit).

Note on RDY* Input:

•Be sure to input "L" to pin RDY* of the target system during the user program execution (only while the RUN status LED on the PC4701's front panel is lit). Inputting "L" to pin RDY* during the user program stopping may cause a malfunction of the emulator.

Notes on HOLD* Input:

•Be sure to input HOLD* of the target system during user program execution (only while the RUN status LED on the PC4701's front panel is lit). If "L" is input to pin HOLD*, the emulator will not work normally.

•When inputting "L" to pin HOLD* to run into the HOLD state, P00 to P52 will be in the HOLD state delaying by 2.5 cycles than the actual MCU (see Table 5.5 and Figure 5.4).

Notes on Setting the Work Area When Starting Up the Emulator Debugger:

•With this product, the emulator uses 32 bytes as a work area in emulation memory. In single-chip mode, set the work area address at 10000h. In memory expansion or microprocessor mode, set the work area address in an area other than SFR area (0000h--003FFh), external area of multiplex bus setting and stack area used by the emulator for reset command execution (0FFF9h--0FFFFh). For more details, see "2.4 (2) Setting the Work Area" (page 25).

•The top address of the work area should be an even-numbered address.

•Set the work area as MAP=INT.

For example, if the work area is set at 02C00h, the emulator uses 32-byte area of 02C00h to 02C1Fh.

( 13 / 84 )

IMPORTANT

Note on Stack Area:

•With this product, a maximum 7 bytes of the user stack is consumed. Therefore, ensure the +7 bytes maximum capacity used by the user program as the user stack area.

If the user stack does not have enough area, do not use areas which cannot be used as stack (SFR area, RAM area which stores data, or ROM area) as a work area. Using areas like this is a cause of user program crashes and destabilized emulator control.

Notes on MAP References and Settings:

•For details on referencing and setting MAP information, see the emulator debugger M3T-PD30 user's manual.

Make settings as follows:

(1)MAP = INT

The emulation memory inside this product becomes effective. Set this at MCU internal ROM debugging.

(2)MAP = EXT

The emulation memory inside this product is not used.

Set this where the MCU internal resource (SFR, RAM) or resources on the target system are used.

•Be sure to set the SFR area and RAM area of the MCU to EXT, and the reserved area of the MCU to INT.

•Be sure to set mappings in word units.

•When setting 0FFF9h to 0FFFFh to EXT:

This product uses the 7 byte area 0FFF9h through 0FFFFh as the stack area. If this 7 byte memory cannot be read or written to, reset cannot be properly effected. As a result, you need to alter the map settings if the condition given below is met.

(1)With the system which shifts from the single-chip mode to memory expansion (or microprocessor) mode, using the 7 byte area of 0FFF9h to 0FFFFh set to EXT.

(2)With the system which starts up in microprocessor mode, using the 7 byte area of 0FFF9h to 0FFFFh set to EXT and there is not enough memory to read or write.

The procedures to alter the MAP settings when the conditions (1) or (2) above are met.

(1)Set the 7 byte area of 0FFF9h to 0FFFFh to INT.

(2)Execute the RESET command by use of emulator debugger M3T-PD30.

(3)Set the stack pointer. (Example)

RESET:	FCLR I
	LDC #0480H, SP --> Set the stack pointer
	(Stop the program after executing this instruction)

(4) Set the 7 byte area 0FFF9h through 0FFFFh to EXT.

( 14 / 84 )

IMPORTANT

Note on Operation When Not Executing the User Program:

•With this product, bit 7 of processor mode register 1 (wait bit PM17) is forcibly set to "1" (with wait) when the user program is not executed (e.g. when the program is stopped or when run-time debugging is being performed). Therefore, if the external area set to 0 wait is accessed by other than the user program (such as debugging operation), one wait is inserted. However, when wait bit PM17 is referenced by the dump window etc. the value set during user program execution is displayed.

Note on Making an MCU file:

•To debug an MCU which has any other size of memory (ROM, RAM), be sure to make an MCU file for it. For details on making an MCU file, see "2.4 (1) Making an MCU File" on page 25. For memory maps of each MCU, refer to the datasheet of the MCU.

Notes on Maskable Interrupts:

•Even if a user program is not being executed (including when run-time debugging is being performed), the evaluation MCU keeps running so as to control the emulation probe. Therefore, timers and other components do not stop running.

If a maskable interrupt is requested when the user program is not being executed (including when run-time debugging is being performed), the maskable interrupt request cannot be accepted, because the emulator disables interrupts. The interrupt request is accepted immediately after the user program execution is started.

•Take note that when the user program is not being executed (including when run-time debugging is being performed), a peripheral I/O interruption is not accepted.

Notes on Address-Match Interrupt:

•To debug address-match interrupts, set a software breaks or hardware break at the top address of the address-match interrupt process. If you set a software breaks or hardware break at an address where an address-match interrupt occurs, the program will run out of control.

•When an address at which an address-match interrupt occurs is executed in one-step mode, the program stops after executing the first instruction after returning from the address-match interrupt processing.

Note on BRK Instruction and BRK Interrupt:

•With this emulator system, a BRK interrupt by a BRK instruction is exclusively used for software break functions. Therefore, you can not use them for your program.

( 15 / 84 )

IMPORTANT

Notes on Software and Hardware Breaks:

•The software break is a debugging function which breaks a program immediately before the system executes an instruction at a specified address. The instruction at the preset address will not be executed.

•The hardware break is a debugging function which breaks a program by setting the detection of an execution of an instruction at a specified address as a break event. The program will break after the instruction at the specified address is executed.

•The software break generates BRK interrupts by substituting the proper instruction to the BRK instruction. Therefore, when referencing the result of a trace in bus mode, "00h" is displayed for the instruction fetch address where a software break is set, and when referencing in disassemble mode, "BRK" instruction is displayed.

•It is not possible to use a software break and a hardware break at the same time. If doing so, it may not operate normally.

•In the area where the MAP setting is EXTERNAL, software breaks cannot be used.

Note on Stop and Wait Modes:

•Do not perform step execution at addresses in the stop or wait mode. It may cause communication errors.

Note on Watchdog Function:

•The MCU's watchdog timer can be used only while programs are being executed. To use it otherwise, disable the watchdog timer.

Note on DMA Transfer:

•With this product, the program is stopped with a loop program to a specific address. Therefore, if a DMA request is generated by a timer or other source while the program is stopped, a DMA transfer is executed. However, make note of the fact that a DMA transfer while the program is stopped may not be performed correctly. Also note that the below registers have been changed to generate a DMA transfer as explained here even when the program is stopped.

DMA0 transfer counter registers TCR0, TCR1 (M16C/62N only)

Note on Pullup Control:

•With this product, ports P0 [7:0] to P5 [7:0] are not pulled up by the pullup control register.

To pull up the ports P0 to P5, apply a resistance to the inside of the emulator. How to apply it, refer to "3.5 Installing and Removing Pullup Resistors" (page 37).

Note: Ports P6 to P10 are pulled up by the pullup control registers.

Note: Pullup control registers themselves can be read and written into properly.

( 16 / 84 )

IMPORTANT

Note on Reading Internal Resources of the MCU:

•When the registers that are listed in Table 1.1 are read with an emulator, those results will be the following (the data in the MCU are not effected).

(1)Results of real-time trace

The data values of the cycles read are not displayed correctly.

(2)Real-time RAM monitor

The data values read are not displayed correctly.

Table 1.1 Resisters and symbols not displayed normally (*1: M16C/62N only)

Resister	Symbol
DMA source pointers 0, 1 (*1)	SAR0, SAR1 (*1)
DMA destination pointers 0, 1 (*1)	DAR0, DAR1 (*1)
DMA transfer counters 0, 1 (*1)	TCR0, TCR1 (*1)
DMA control resisters 0, 1 (*1)	DM0CON, DM1CON (*1)

Note on Protect Register (PRC2):

•Make note of the fact that the protect is not canceled when protect register (PRC2), which enables writing in the port P9 direction register and the SI/Oi control register, is changed with the below procedure.

(1)Step execution of the "instruction for setting ("1") PRC2"

(2)Setting the break point from the instruction for setting ("1") PRC2 to when the port P9 direction register and SI/Oi control register are set.

(3)Setting "("1") PRC2" from the dump window or script window

Note on Accessing Address 00000h:

•With M16C/60 Series MCUs, when a maskable interrupt is generated, the interrupt data (interrupt No. and interrupt request level) stored in address 00000h is read out. Also, the interrupt request bit is cleared when address 00000h is read out. Consequently, when the address 00000h readout instruction is executed or when address 00000h is read out in the cause of a program runaway, a malfunction occurs in that the interrupt is not executed despite the interrupt request, because the request bit of the highest priority interrupt factor enabled is cleared.

For this malfunction, when the reading out to the address 00000h is generated excluding the interrupt, the yellow LED lights up to alarm. When this LED lights, there is a possibility of wrong access to address 00000h, therefore check the program. This LED is turned off by the system reset switch of the emulator main unit.

( 17 / 84 )

IMPORTANT

Note on Differences Between the Actual MCU and Emulator:

•Operation of the emulator differs from that of the actual MCU as listed below.

(1)Reset condition

Set the time for starting up (0.2 Vcc to 0.8 Vcc) 1 s or less.

(2)Initial values of MCU's internal resources at power-on

(3)Internal memories (ROM and RAM) capacities etc.

With this emulator system, regardless of ROM and RAM of the MCU you use, all the areas other than the SFR area can be read and written into.

(4)Characteristics of ports P0 to P5

Ports P0 to P5 are connected via emulation circuits. The device used for the port emulation circuit is the IC21 (ALTERA EPF6016QC208-2).

(5)Oscillator circuit

•Make note that in the oscillator circuit where a resonator is connected between pins XIN and XOUT, oscillation does not occur because a flexible cable, buffer IC and other devices are used between the evaluation MCU and the target system. It is same for sub-clock oscillators (XCIN and XCOUT).

•For notes on when using the oscillator circuit on the target system, refer to "3.3 (2) Using the Oscillator Circuit on the Target System" (page 31).

(6)A-D conversion function

As a flexible cable and other devices are used between the evaluation MCU and the target system, some characteristics are slightly different from those of the actual MCU.

(7)DBC, single-step and BRK instruction interrupt vector table addresses

As the emulator uses the DBC, single-step and BRK instruction interrupt vector table addresses, when reading these addresses, the downloaded data cannot be read (see Table 1.2).

Table 1.2 Vector table addresses for the emulator

Factor of interruption	Vector table addresses	Data read
DBC*1	FFFF4h--FFFF7h	Indefinite
Single-step*1	FFFECh--FFFEFh	Indefinite
BRK instruction	FFFE4h--FFFE7h	Indefinite

*1 Interruption for the emulator only

(8)Address and status of BHE*

When the internal RAM or ROM area of the MCU is accessed during user program execution, the actual MCU retains a preceding address and status of BHE*, while this product does not.

(9)Status of a data bus

In stop or wait mode, the actual MCU retains a preceding status of a data bus, while with this product a data bus is floating.

(10)ALE signal

When the internal RAM or SFR area of the MCU is accessed during user program execution, with the actual MCU, ALE output is fixed to Low, while this product outputs ALE signal.

( 18 / 84 )

IMPORTANT

Note on Debugging Operations After Releasing a Reset from the Target:

•Do not execute debugging operations such as setting a software or hardware break, runtime debugging after releasing a reset from the target system until an interrupt stack pointer (ISP) is set in the user program.

Note on Emulating External Area:

•To emulate the external area using emulation memory in this product, set 0 wait (8 MHz) or less, or 1 wait.
