[COM positions and ADRAM addresses]
4. General output port set
[Command format]
[Set data and set state of general output port]
(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
it becomes the ground potential. Therefore, the fluorescent display tube cannot be driven.
