GENERAL OUTPUT PORT SET COMMAND

The General Output Port Set Command is used to specify the general output port status. The general output port is used

to control other input/output devices as well as turn on the LED Display. When the general output port is set to "HIGH",

the output is equivalent to the VDD voltage. When the general output port is set to "LOW" Level, the output becomes

ground potential. The command format is given below.
