4096 words ✕ 10 bits

256 words ✕ 4 bits

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.

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.

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 P11, P12 and P13 are also used as CNTR1, CNTR0 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 and output structure can be switched by software.

Ports P20 and P21 are also used as AIN0 and AIN1, respectively.

Two independent I/O; CNTR1 and CNTR0 pins are also used as ports P11 and P12, respectively.

1-bit input; INT pin is also used as port P13.

Three independent I/O;

SIN, SOUT, and SCK are also used as ports P00, P01, and P02, respectively.

Four independent input; AIN0, AIN1, AIN4, AIN5 are also used as P20, P21, D2 and D3, respectively.

8-bit programmable timer/event counter with two reload registers and PWM output function.

16-bit timer (fixed dividing frequency) (for watchdog)

10-bit wide, This is equipped with an 8-bit comparator function.
