FUNCTION

Port 0A, port 0B, serial interface, clock

stop release and A/D converter input/

outputs.

• P0A3 to P0A0

• 4-bit input/output port

• Input/output settable bit-wise

• P0B3 to P0B0

• 4-bit CMOS input/output port

• Input/output settable bit-wise

• SDA, SCL

• SDA : Serial data input/output

• SCL : Serial clock input/output

• SCK0, SO0, SI0

• SCK0 : Serial clock input/output

• SO0 : Serial data output

• SI0 : Serial data input

• RLSSTOP

• Clock stop release

• ADC

• Analog input to 6-bit resolution A/D

converter

Input external interrupt request signal.

Either the rising edge or falling edge may

be selected as the effective edge for an

interrupt request.

Watchdog 32 kHz oscillator power supply.

Connects watchdog 32 kHz oscillator.

A 32 kHz crystal resonator should be

connected.

Pin for ground.

Pins 33 and 53 are connected within the

chip, but should also be connected to the

same potential externally taking into

condideration the characteristics of the

IDC (Image Display Controller).

Port 2A and serial interface input/outputs.

• P2A3 to P2A0

• 4-bit input/output port

• Input/output set capability as bit-wise

• SO1, SCK1, SI1

• SO1 : Serial data output

• SCK1 : Serial clock input/output

• SI1 : Serial data input
