4. 4 Writing to chip (WRAL)
CS
SK
DO
DI
To write the same 16-bit data to the entire memory address space, change CS to high, and then input the
WRAL instruction, an address, and 16-bit data following the start bit. Any address can be input. 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 WRAL
instruction. For details of the clock pulse monitoring circuit, refer to “
Write due to Erroneous Instruction Recognition ”.
