Power supply plus side
LSI internal logic block minus power supply
In Li specification products, connect a capacitor between BAK and V
DD
to prevent incorrect operation.
Power supply minus side
External component connections differ depending on mask options
and other factors.
In products for Ag use, connect V
SS
1 to the power supply minus side.
In other products, connect V
SS
2 to the power supply minus side.
The pins other than the minus pin are used for the LCD driver power
supply.
Connections for the LCD drive voltage boost (cut) capacitor.
Used for real-time clock and the system clock.
Connected to OSC-IN or OSC-OUT and used for the oscillator phase
compensation capacitor. Can only be used in the chip product.
Dedicated input port
Includes either a 10 (32 ms), 8 (8 ms), or 2 (2 ms) chattering
exclusion circuit (PLA mask option).
*
These values are for the case where a 32.768 kHz crystal is used.
Pull-down resistors are built in.
Dedicated input port
Input connections for acquiring data to internal RAM
Pull-down resistors are built in.
I/O port
Input connections for acquiring data to internal RAM
Output connections for data output from internal RAM
The input or output state can be switched by two instructions.

Dedicated output
This pin can output a signal modulated either at 4 kHz or 2 kHz, or at
4 kHz or 1 kHz under program control. Alternatively, an unmodulated
signal can be output.
