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 V
DD
voltage, and when at the "Low" level,
it becomes the ground potential. Therefore, the fluorescent display tube cannot be driven.
