Description
Typical 32.768kHz crystal is connected across OSCIN/OSCOUT for
oscillation, R/C oscillation mode is also available.
Input pins with pull-down Tr or "L-level hold" Tr.
External interrupt request control input pin.
System reset pin with pull-down resistance.
Output only for outputting 4kHz/2kHz/1kHz modulation signal. Also can be
used to output non-modulation signal.
Power supply pin for logic unit inside LSI. When using Li version, a
capacitor must be connected across GND and VDD to prevent logic unit
from malfunctioning.
For Ag-B mode positive power supply pin.
For Li-B(EXTV) mode positive power supply pin.
Negative power supply pin.
Pins for connecting voltage step-up (step-down) capacitor.
Output pins for LCD panel common plate.
The following pins are used in each case.
