VII.4 I/O Port
The I/O registers are bi-directional tri-state I/O ports. The I/O ports can be defined as "input" or "output" pins by
the I/O control registers under program control. The I/O data registers and I/O control registers are both readable
and writable. The I/O interface circuit is shown in Fig.11.
