4. General output port set

(specifies the general output port status)

The general output port is an output for 4-bit static operation.

It is used to control other I/O devices and turn on LED. (Static operation.)

The fluorescent display tube cannot be driven by this output port, because when at the "High"

level this output becomes the VDD voltage and when at the "Low" level it becomes the ground

potential.
