Description

Typical 32.768kHz crystal is connected across OSCIN/OSCOUT for Oscillation; R/C

oscillation mode also available.

Connected to OSCOUT for compensation capacitor.

Port for input only with chattering eliminator for CK10 (32ms), CK8 (8ms) & CK6

(2ms). (PLA mask option).

Input ports.

Output ports.

Input/Output ports. After power-on reset, sets as input mode.

Input/Output ports. After power-on reset, sets as input mode.

External interrupt request control input pin.

System reset pin.

Output only for outputting signal to drive transistor for light.

Output only for outputting 4kHz/2kHz/1kHz modulation signal. Also can be used to

output a non-modulation signal.

(+)Power supply pin.

Power supply pin for logic unit inside LSI. When using Li version, a capacitor must be

connected across GND and VDD to prevent the logic unit from malfunctioning.

(--) Power supply pin.

* For Ag version, apply (--) side to both VSS0 & VSS1.

For other than Ag version, apply (--) side to both VSS0 & VSS2.

LCD power supply pin.

Pins for connecting the voltage step-up (step-down) capacitor.

Output pins for LCD panel common plate.

The following pin is used in each case.
