Four independent I/O ports.
Input is examined by skip decision.
Ports D2 and D3 are equipped with a pull-up function and a key-on wakeup function. Both func-
tions can be switched by software.
Ports D2 and D3 are also used as ports C and K, respectively.
4-bit I/O port; each pin is equipped with a pull-up function and a key-on wakeup function. Both
functions can be switched by software.
4-bit I/O port; each pin is equipped with a pull-up function and a key-on wakeup function. Both
functions can be switched by software.
Ports P12 and P13 are also used as CNTR and INT, respectively.
2-bit I/O port; each pin is equipped with a pull-up function and a key-on wakeup function. Both
functions can be switched by software.
Ports P20 and P21 are also used as AIN0 and AIN1, respectively.
1-bit I/O; Port C is also used as port D2.
1-bit I/O; Port K is also used as port D3.
1-bit I/O; CNTR pin is also used as port P12.
