A4 Dec 29, 2003 5/13 Function Descriptions 1.0 Commands Commands set the display mode and status of the VFD driver. The first 1 byte input to the AD6312 through the DIN pin after the STB pin has fallen is regarded as a command. If STB is set high while a commands/data are transmitted, serial communication is initialized, and the commands/data being transmitted are invalid (however, the commands/data previously transmitted remain valid). 1.1 Display mode setting commands These commands initialize the AD6312 and select the number of segments and the number of grids (4 grids & 16 segments to 11 grids & 11 segments to). 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.
