8-bit Micro-controller
Master: output pin, Slave: input pin. This pin shared with
PORT60.
Output pin for serial data transferring. This pin shared with
PORT61.
Input pin for receiving data. This pin shared with PORT62.
Comparator input pins. Shared with PORT63, PORT64 and
PORT65.
Current DA output pin. It can be a control signal for sound
generating.
Shared with PORT66.
PORT 5 can be INPUT or OUTPUT port each bit.
PORT 6 can be INPUT or OUTPUT port each bit.
Internal pull high.
PORT 7 can be INPUT or OUTPUT port each bit.
Internal Pull high function.
Auto key scan function.
Interrupt function.
PORT 8 can be INPUT or OUTPUT port each bit.
Shared with LCD Segment signal.
PORT 9 can be INPUT or OUTPUT port each bit.
Shared with LCD Segment signal.
PORT B can be INPUT or OUTPUT port each bit.
Shared with LCD Segment signal.
PORT C can be INPUT or OUTPUT port each bit.
Shared with LCD Segment signal.
Interrupt sources which has the same interrupt flag. Any pin from
PORT70 to PORT73 has a falling edge signal, it will generate a
interruption.
Interrupt sources which has the same interrupt flag. Any pin from
PORT74 to PORT76 has a falling edge signal, it will generate a
interruption.
Interrupt source. Once PORT77 has a falling edge or rising edge
signal (controlled by CONT register), it will generate a
interruption.
Test pin into test mode for factory test only. Connect it ground in
application.
Low reset
Differential Energy Detector input pin
It can detect external analog signal
