Eight independent I/O ports;

Ports D6 and D7 are also used as CNTR0 and CNTR1, respectively.

The output structure is switched by software.

4-bit I/O port; a pull-up function, a key-on wakeup function and output structure can be switched

by software.

4-bit I/O port; a pull-up function, a key-on wakeup function and output structure can be switched

by software.

3-bit I/O port; ports P20, P21 and P22 are also used as SCK, SOUT and SIN, respectively.

2-bit I/O port ; ports P30 and P31 are also used as INT0 and INT1, respectively.

4-bit I/O port ; ports P60–P63 are also used as AIN0–AIN3, respectively.

8-bit timer with a reload register is also used as an event counter.

Also, this is equipped with a period/pulse width measurement function.

8-bit timer with a reload register.

8-bit timer with a reload register is also used as an event counter.
