4. 2 Writing data (WRITE)
DO
CS
SK
DI
To write 16-bit data to a specified address, change CS to high and then input the WRITE instruction,
address, and 16-bit data following the start bit. The write operation starts when CS goes low. There is no
need to set the data to 1 before writing. If the clocks more than the specified number have been input, the
clock pulse monitoring circuit cancels the WRITE instruction. For details of the clock pulse monitoring
circuit, refer to “ Function to Protect Against Write due to Erroneous Instruction Recognition ”.
