Commands

Commands set the display mode and status of the FIP driver.

The first 1 byte input to the
PD16312 through the DIN pin after the STB pin has fallen is regarded as a command.

If STB is set high while commands/data are transmitted, serial communication is initialized, and the

commands/data being transmitted are invalid (however, the commands/data previously transmitted remain valid).

(1) Display mode setting commands

These commands initialize the
PD16312 and select the number of segments and the number of grids (1/4 to

1/11 duty, 11 segments to 16 segments).

When these commands are executed, the display is forcibly turned off, and key scanning is also stopped. To

resume display, the display command “ON” must be executed. If the same mode is selected, however, nothing

happens.
