Input/Output D0–D3 I/O
ports
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 functions can be switched by software.
Ports D2 and D3 are also used as AIN4, and AIN5, respectively.
P00–P03 I/O
4-bit I/O port; each pin is equipped with a pull-up function and a key-on wakeup function.
Both functions and output structure can be switched by software.
Ports P00, P01 and P02 are also used as SIN, SOUT and SCK, respectively.
P10–P13 I/O
4-bit I/O port; each pin is equipped with a pull-up function and a key-on wakeup function.
