SC16313
FUNCTION DESCRIPTION
DISPLAY RAM ADDRESS
Data transmitted from an external device to SC16313 via the serial interface are stored in the display RAM
and are assigned addresses. The RAM addresses of SC16313 are given below in 8 bits unit.

Only the lower 4 bits of the addresses assigned to SG9 through SG12 are valid, and the higher 4 bits are
ignored.
SC16313 KEY MATRIX & KEY INPUT DATA STORAGE RAM
SC16313 key matrix consists of 8 x 2 arrays as shown below:
KEY1
KEY2
The data of each key is stored in key-input data RAM as illustrated below. They are read by a READ
command, starting from the least significant bit. When the most significant bit of the data (SG8, b7) has been
read, then the least significant bit of the next data (SGI, b0) will be read.

COMMANDS
Commands set the display mode and status of SC16313. The first byte (b0 to b7) inputted to SC16313 via
the DIN pin after STB pin has fallen is regarded as a command. If for some reason the STB pin is made
“HIGH” while data or commands are being transmitted, the serial communication is initialized, and the
