The data of each key is stored as illustrated below, and is read with the read command, starting from the least

significant bit.

3. LED PORT

Data is written to the LED port with command, starting from the least port’s least significant bit. ”L” output when

the bit of this port is 0, and “H” output when the bit is 1. The data of bits after the 5th bit are ignored.

Remark: On power application, all the LED ports are “L” output.

4. COMMANDS

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

The first 1 byte input to the SC16315 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 SC16315 and select the number of segments and grids (1/4- to 1/12- duty, 16

segments to 24 segments).

When these commands are executed, the display and key scanning are forcibly turned off. Therefore, in order to

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

will happen.
