I/O
8-bit I/O ports in CMOS, having a direction register to select an input or output.
Each pin is set as an input port or output port. An input port can be set for a
pull-up or for no pull-up in 4-bit unit by program.

I/O ports having equivalent functions to P0.
Input port
Input pin for the _N__M___I_ interrupt.
Pin states can be read by the P8_5 bit in the P8 register.
I : Input
O : Output
I/O : Input and output
NOTES:
1. When use VCC1 ≥ VCC2, contacts due to some points or restrictions to be checked.
2. Ports P11 to P14 are provided in the 128-pin version only.
