Set output mode, Segment output or GPO output.
P2 to P0: Select changing port number. (SEG23 to SEG26 ports are SEG mode/GPO mode selectable)
In case GPO output is selected, Terminal output data is set by GPOSET command.
Ex) In case SEG 26 port assigned to GPO,
If GPO1 data is "H", GPO1 (SEG26) port outputs "H" (VLCD Level).
If GPO1 data is "L", GPO1 (SEG26) port outputs "L" (VSS level).
Output terminal state under the P2 to P0 set condition is listed below

In case SEG port is switched to the GPO port, DDRAM address and Blink RAM address do not change.
In this case DDRAM address and Blink RAM address, selected GPO output mode is dummy address.
