PT6313-S

FUNCTION DESCRIPTION

COMMANDS

Commands determine the display mode and status of PT6313-S. A command is the first byte (b0 to b7)

inputted to PT6313-S via the DIN Pin after STB Pin has changed from “HIGH” to “LOW” State. If for

some reason the STB Pin is set to “HIGH” while data or commands are being transmitted, the serial

communication is initialized, and the data/commands being transmitted are considered invalid.

COMMAND 1: DISPLAY MODE SETTING COMMANDS

PT6313-S provides 4 display mode settings as shown in the diagram below: As stated earlier a

command is the first one byte (b0 to b7) transmitted to PT6313-S via the DIN Pin when STB is “LOW”.

However, for these commands, the bits 4 to 6 (b3 to b5) are ignored, bits 7 & 8 (b6 to b7) are given a

value of “0”.

The Display Mode Setting Commands determine the number of segments and grids to be used (1/4 to

1/8 duty, 12 to 8 segments).

When Power is turned “ON”, the 8-digit, 8-segment mode is selected.
