I/O

CMOS I/O ports. A direction register determines whether each

pin is used as an input port or an output port. For input ports,

pull-up resistor is selectable for every unit of 4 bits.

However, P8_5 output is N-channel open drain output and does

not have a pull-up resistor.

Port P8_5 shares the pin with

NMI, so that the NMI input level

can be read from the P8 register P8_5 bit.
