8-bit OTP Micro-controller

PORT8 can be INPUT or OUTPUT port each bit.

Internal pull high.

PORT85 ~ P87 are shared with ADC input

PORT8(0~3) have wake-up functions(set by RE PAGE0)

PORT9 can be INPUT or OUTPUT port each bit.

PORT9 are shared with LCD Segment signal.

PORTB can be INPUT or OUTPUT port each bit.

PORTB are shared with LCD Segment signal.

PORTC can be INPUT or OUTPUT port each bit.

PORTC(7:5) are shared with LCD Segment signal.

Interrupt sources. Once PORT70 has a falling edge or rising edge signal

(controlled by CONT register), it will generate a interruption.

Interrupt sources which has the same interrupt flag. Any pin from PORT71

has a falling edge signal, it will generate a interruption.

Interrupt sources which has the same interrupt flag. Any pin from PORT72

has a falling edge signal, it will generate a interruption.

Interrupt sources which has the same interrupt flag. Any pin from PORT73

has a falling edge signal, it will generate a interruption.

Low reset
