FUNCTION DESCRIPTION
COMMANDS
Commands determine the display mode and status of PT6315-S. A command is the first byte (b0 to b7)
inputted to PT6315-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
PT6315-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 PT6315-S via the DIN Pin when STB is “LOW”.
However, for these commands, the bits 5 to 6 (b4 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 these commands are executed, the display is forcibly turned off, the
key scanning stops. A display “ON” command must be executed in order to resume display. If the same
mode setting is selected, no command execution is take place, therefore, nothing happens.
When Power is turned “ON”, the 8-digit, 8-segment mode is selected.
