3.11 Output Pin Control Command
This command selects the format of pin output of the option (A, B, or C) specified by the initial status setting
command (because this is a 2-byte command, input of 16 bits is necessary if this command is input more than once
successively).
Remark
This command is invalid when RGB + RGB compatible BLK output is selected.
(1) With MSB first (The command is input from MSB (D15).)

Row specification control
Specify to which of the VC1 or VC2 pin the character signal is to be output in row units (or 12-column units).
•
Output pin control
Output of the VC1 and VC2 pin can be selected from A, B, or C by using the initial status setting command
(the blanking signal is output in the same manner).
