5. Status Read
It is possible to read four kinds of status using this command.
6. Write Data
The 8-bit display data is written in the display data RAM. After writing the display data, the column address is
automatically incremented. When writing the successive display data after setting the first column address
using the column address set command, it is unnecessary to set the column address each time.
For the serial interface, the displayed data is written in the unit of 8 bits.
7. Read Data
The 8-bit display data is read from the display data RAM. After reading the display data, the column address is
automatically incremented. When reading the successive display data after setting the first column address
using the column address set command, it is unnecessary to set the column address each time. For reading
display data just after the column address set, a dummy read is needed.
The serial interface also needs dummy reading.
8. ADC Select
Forward or reverse can be selected for the correlation between the column address and the segment output
terminal of the display data RAM. Make sure the RAM corresponds to the address.

“1” : Shows that the IC inside is executing a command operation or a reset operation.
When the Busy flag is output, the command is not received. If the cycle time of the command is
satisfied with the specified value, Busy flag confirmation is not needed.
“0” : Shows that the command is ready
Shows forward or reverse correlation between column address and segment output terminal of the
display data RAM
The setting is executed using the ADC select command.

Display normal operation status
“1” : Shows the display OFF status.
Display all-OFF status.
Shows that the S-4543A is executing initialization by RESX input or Reset command.
