4. General output port set
(specifies the general output port status)
The general output port is an output for 2-bit static operation.
It is used to control other I/O devices and turn on LED. (static operation)
When at the “High” level, this output becomes the VDD voltage, and when at the “Low” level, it becomes the
ground potential. Therefore, the fluorescent display tube cannot be driven.
