I/O ports fro CMOS. Each port can be programmed for nput or
output under the control of the direction register. An input port
can be set, by program, for a pull-up resistor available or for no
pull-up resistor available in 4-bit units
I/O ports having equivalent functions to P0
(P7
0 and P71 are ports for the N-channel open drain output.)
I/O ports having equivalent functions to P0

NOTES:
1. Ports P0 to P5 function as bus control pins when using memory expansion mode or microprocessor mode. They
cannot be used as I/O ports.
2. Port P1 functions as I/O port when the microcomputer is placed in memory expansion mode or microprocessor
mode and all external data buses are selected as 8-bit buses.
