data/command being transmitted is considered invalid. (However, the data/command already transmitted

remains valid)

Command 1: display mode setting command

This command initializes the SC16313 and selects the number of segments and number of grids (4 to 8

grids, 12 to 8 segments).

When this command is executed, display is forcibly turned off, and key scanning is also stopped. To resume

display, a display ON command must be executed.

SC16313 provides 4 display mode settings as shown in the diagram below. The bits 4 to 6 (b3 to b5) are

ignored, bits 7 & 8 (b6 to b7) are given a value of “0”.

On power application, the 8-digit, 8-segment mode is selected.

Display Mode Settings:

000: 4 digits, 12 segments

001: 5 digits, 11 segments

010: 6 digits, 10 segments

011: 7 digits, 9 segments

100: 8 digits, 8 segments

Command 2: data setting command

This command sets data write or data read modes. The data setting command, the bits 6 and 5 (b5, b4) are

ignored, bit 8 and bit 7 (b7, b6) are given the value of “01”. Please refer to the diagram below.

On power application, the normal operation mode and address increment mode are set.

Data write & read mode settings:

00: write data to display memory

10: read key data

Address increment mode settings (display

memory):

0: increment address after data has been written

1: fixes address

Test mode settings:

0: normal operation mode

1: test mode

Command 3: address setting command

This command sets an address of the display memory. The address is considered valid if it has a value of

“00H”to “0FH”. If the address is set to 10H or higher, the data is ignored until a valid address is set.

On power application, the address is set to “00H”.

Please refer to the diagram below.
