8-bit I/O ports for CMOS. Each port can be programmed for input 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 resister available in
4-bit units
(P70 and P71 are ports for the N-channel open drain output.)
