VII.4 I/O Ports

The I/O registers, Port 6 ~ Port 9, are bi-directional tri-state I/O ports. Port 7 can be pulled-high internally by

software control. The I/O ports can be defined as "input" or "output" pins by the I/O control registers (IOC6 ~ IOC9 )

under program control. The I/O registers and I/O control registers are both readable and writable. The I/O interface

circuit is shown in Fig.11.
