I/O
8
bits I/O port of the CMOS.
Have a direction register to select input and output, and can do it to an input port
or an output port every 1 terminal.
The input port can select having pulling up resistance or not by a 4 bits unit by a
program.
(but the output of P7_0, P7_1 is
N
channel open drain.)
