∙ I/O port

Input-output port

: 3 ports

× 4 bits

Input port

: 1 port

× 4 bits

Output port

: 1 port

× 4 bits

( 8 out of the 34 LCD driver outputs can be used as

output-only ports by mask option. )

∙ LCD driver

: 34 outputs

(1) At 1/4 duty and 1/3 bias

: 120 segments (max.)

(2) At 1/3 duty and 1/3 bias

: 93 segments (max.)

(3) At 1/2 duty and 1/2 bias

: 64 segments (max.)

Voltage Regulator for LCD Driver (selectable by mask option)

The LCD panel display is stable regardless of temporary supply voltage drop, because the voltage

generated by the voltage regulator for LCD driver is supplied to the bias voltage generator as a

reference voltage.

LCD Operating Voltage

When the voltage regulator for LCD driver is used

: 3.6 V ( Duty cycle = 1/4 or 1/3 )

: 2.4 V ( Duty cycle = 1/2 )

When the voltage regulator for LCD driver is not used

: 4.5 V ( Duty cycle = 1/4 or 1/3 )

: 3.0 V ( Duty cycle = 1/2 )

∙ Buzzer driver

: 1 output ( 4 output modes selectable )

∙ Serial port

: Synchronous 8-bit transfer

Selectable as external clock / internal clock

Selectable as MSB first / LSB first

∙ Capture circuit

: 2 channels ( 32Hz, 64Hz, 128Hz, 256Hz )

∙ Battery check circuit

: 1 ( incorporated into the input-only port )

∙ Watchdog timer

∙ Interrupt

External interrupt

: 2 sources

Internal interrupt

: 8 sources
