3. Watchdog timer option

A runaway detection function (watchdog timer) can be selected as an option.

4. Port output type options

• The output type of each bit (pin) in ports P0, P1, P2, P3 (except for the P33/HOLD pin), P4, P5, P6, P7, P9, PA,

PB, and PC can be selected individually from the following two options. (in1-bit units)

Option

Circuit

Conditions and notes

Open-drain output

DSB

Output data

Input data

The ports P2, P3, P5, P6, and P9 inputs have

Schmitt characteristics.

P7, PA, and PB are output-only ports.

Output with built-in pull-up

resistor

DSB

Output data

Input data

The ports P2, P3, P5, P6, and P9 inputs have

Schmitt characteristics.

The CMOS outputs (ports P2, P3, P6, P9, and

PC) and the pull-up MOS outputs (P0, P1, P4,

P5, P7, PA, and PB) are distinguished by the

drive capacity of the p-channel transistor.

• The two options can be specified for P8 (in 1-bit units)
