DESCRIPTION

µ

PD75108 is a 4-bit single-chip microcomputer integrating timer/event counters, serial interface, and vector
interrupt function, in addition to a CPU, ROM, RAM, and I/O ports, on a single chip. Operating at high speeds,
the microcomputer allows data to be manipulated in units of 1, 4, or 8 bits. In addition, various bit manipulation
instructions are provided to reinforce I/O manipulation capability. Equipped with I/Os for interfacing with
peripheral circuits operating on a different supply voltage, outputs that can directly drive LEDs, and analog
inputs,

µ

PD75108 is suitable for controlling such systems as VTRs, acoustic products, button telephones, radio
communications equipment, and printers. A pin-compatible EPROM model is also available for evaluation of
system development and small-scale production of application systems.

Detailed functions are described in the following user’s manual. Be sure to read it for designing.

3.5 NOTES ON USING THE P00/INT4, AND RESET PINS

In addition to the functions described in Sections 3.1 and 3.2, an exclusive function for setting the test mode,

in which the internal fuctions of the

µ

PD75108 are tested (solely used for IC tests), is provided to the P00/INT4

and

RESET

pins.

If a voltage exceeding V

DD is applied to either of these pins, the

µ

PD75108 is put into test mode. Therefore,

even when the

µ

PD75108 is in normal operation, if noise exceeding the VDD is input into any of these pins, the

µ

PD75108 will enter the test mode, and this will cause problems for normal operation.

As an example, if the wiring to the P00/INT4 pin or the

RESET

pin is long, stray noise may be picked up

and the above montioned problem may occur.

Therefore, all wiring to these pins must be made short enough to not pick up stray noise. If noise cannot

be avoided, suppress the noise using a capacitor or diode as shown in the figure below.

• Connect a capacitor across P00/INT4 and

RESET

, and VDD.

• Connect a diode across P00/INT4 and

RESET

, and VDD.

5.5 TIMER/EVENT COUNTER

µ

PD75108 contains two channels of timer/event counters.

These two channels are almost identical in terms of configuration and function except the count pulse (CP) that

can be selected and the function to supply clocks to the serial interface.

The functions of the timer/event counter include:

• Programmable interval timer operation

• Output of square wave at an arbitrary frequency to PTOn pin

• Event counter operation

• Input of TIn pin signal as external interrupt input signal

• Dividing TIn pin input by N to output to PTOn pin (frequency divider operation)

• Supply of serial shift clock to serial interface circuit (channel 0 only)

• Reading counting status

5.7 PROGRAMMABLE THRESHOLD PORT (ANALOG INPUT PORT)

µ

PD75108 is equipped with a 4-bit analog input port (consisting of PTH00 to PTH03 pins) whose threshold voltage

is programmable.

This programmable threshold port is configured as shown in Figure 5-6.
The threshold voltage (V

REF) can be changed in 16 steps (VDD × 0.5/16 – VDD × 15.5/16), and analog signals can be

directly input.

When V

REF is set to VDD × 7.5/16, the programmable threshold port can also be used as a digital signal input port.

5.8 BIT SEQUENTIAL BUFFER .... 16 BITS

The bit sequential buffer is a data memory specifically provided for bit manipulation. With this buffer,
addresses and bit specifications can be sequentially up-dated in bit manipulation operation. Therefore, this
buffer is very useful for processing long data in bit units.

Remarks:

For the pmem.@L addressing, the specification bit is shifted according to the L register.

Fig. 5-7 Bit Sequential Buffer Format

5.9 POWER-ON FLAG (MASK OPTION)

The power-ON flag (PONF) is set to only when the power-ON reset circuit operates and power-ON reset signal
has been generated (see Fig. 8-1).

The PONF flag is mapped at bit 0 of memory space address FD1H, and can be manipulated by a bit manipulation
instruction. However, it cannot be set by the SET1 instruction.

6. INTERRUPT FUNCTIONS

The µPD75108 has 7 different interrupt sources and can perform multiplexed interrupt processing with
priority assigned.

In addition to that, the

µ

PD75108 is also provided with two types of edge detection testable inputs.

The interrupt control circuit of the

µ

PD75108 has these functions:

• Hardware controlled vector interrupt function which can control whether or not to accept an interrupt by

using the interrupt enable flag (IExxx) and interrupt master enable flag (IME).

• The interrupt start address can be arbitrarily set.

• Multiplexed interrupt function that can specify priority by the interrupt priority selector register (IPS).

• Interrupt request flag (IRQxxx) test function (an interrupt generation can be confirmed by means of

software).

• Standby mode release (Interrupts to be released can be selected by the interrupt enable flag).

representation and description methods of the instruction (for details, refer to RA75X Assembler Package

several operands. The uppercase characters, +, and – are keywords and must be described as is.

Describe an appropriate numeric value or label as immediate data.

The symbols in the register and flag symbols can be described as labels in the places of mem, fmem,
pmem, and bit (for details, refer to

(4) Machine cycle field

In this field, S indicates the number of machine cycles required when an instruction having a skip

function skips. The value of S varies as follows:

• When no instruction is skipped ........................................................................ S = 0

• When 1-byte or 2-byte instruction is skipped................................................. S = 1

• When 3-byte instruction (BR ! adder or CALL ! adder) is skipped .............. S = 2

Note

: The GETI instruction is skipped in one machine cycle.

One machine cycle equals to one cycle of the CPU clock Φ, (= tCY), and can be changed in three steps

depending on the setting of the processor clock control register (PCC).

of the oscillator circuit. For instruction execution time, refer to AC Characteristics.

2: Time required for oscillation to stabilize after V

DD has come to MIN. of oscillation volrage range

or the STOP mode has been released.

s.

Note: When using the oscillation circuit of the system clock, wire the portion enclosed in dotted line

in the figures as follows to avoid adverse influences on the wiring capacity:

• Keep the wiring length as short as possible.

• Do not cross the wiring over the other signal lines. Also, do not route the wiring in the vicinity
of lines through which a high alternating current flows.

• Always keep the ground point of the capacitor of the osccillator circuit at the same potential
as V

SS. Do not connect the ground pattern through which a high current flows.

• Do not extract signals from the oscillation circuit.

1 STATIC ELECTRICITY (ALL MOS DEVICES)

Exercise care so that MOS devices are not adversely influenced by static electricity while being

handled.

The insulation of the gates of the MOS device may be destroyed by a strong static charge.
Therefore, when transporting or storing the MOS device, use a conductive tray, magazine case,
or conductive buffer materials, or the metal case NEC uses for packaging and shipment, and use
grounding when assembling the MOS device system. Do not leave the MOS device on a plastic
plate and do not touch the pins of the device.

Handle boards on which MOS devices are mounted similarly .

2 PROCESSING OF UNUSED PINS (CMOS DEVICES ONLY)

Fix the input level of CMOS devices.

Unlike bipolar or NMOS devices, if a CMOS device is operated with nothing connected to its
input pin, intermediate level input may be generated due to noise, and an inrush current may flow
through the device, causing the device to malfunction. Therefore, fix the input level of the device
by using a pull-down or pull-up resistor. If there is a possibility that an unused pin serves as an
output pin (whose timing is not specified), each pin should be connected to V

DD or GND through

a resistor.

Refer to “Processing of Unused Pins” in the documents of each devices.

3 STATUS BEFORE INITIALIZATION (ALL MOS DEVICES)

The initial status of MOS devices is undefined upon power application.

Since the characteristics of an MOS device are determined by the quantity of injection at the
molecular level, the initial status of the device is not controlled during the production process. The
output status of pins, I/O setting, and register contents upon power application are not guaranteed.
However, the items defined for reset operation and mode setting are subject to guarantee after
the respective operations have been executed.

When using a device with a reset function, be sure to reset the device after power application.
