CMOS I/O ports. Each port has a corresponding direction
register with which each pin can be set to input or output. For
input ports, pull-up resistor is selectable for every unit of 4 bits.
I/O 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.
Note:
1. The CAN module is only in the M16C/5M Group.
