SC16315S

FUNCTIONAL DESCRIPTION

Commands

Commands determine the display mode and status of SC16315S. A command is the first byte (b0 to b7)

inputted to SC16315S via the DIN Pin after STB Pin has changed from “HIGH”to “LOW”State. For some reason,

if 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.

COMMAND1: Display mode setting commands

SC16315S 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 SC16315S 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). The display will be forcibly turned off and the key scanning will stop when these commands

are executed. In order to resume display, a display command “ON”must be executed. 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.

COMMAND 2: Data setting commands

The Data Setting Commands executes the Data Write or Data Read Modes for SC16315S. The Data Setting

Command, the bits 5 and 6 (b4, b5) are ignored, bit 7 (b6) is given the value of “1”while bit 8 (b7) is given the

value of “0”. Please refer to the diagram below.

When power is turned ON, the bit 4 to bit 1 (b3 to b0) are given the value of “0”.
