WRITE
The write instruction is followed by 16 bits of data to be written into the specified address. After the
last bit of data is put on the DI pin, the CS pin must be brought low before the next rising edge of the
SK clock. This falling edge of the CS initiates the self-timed programming cycle. The DO
indicates the Busy/Ready status of the chip if the CS is brought high after a minimum of ‘tCS’.
DO=logical "0" indicates that programming is still in progress. DO=logical "1" indicates that the
register at the address specified in the instruction has been written with the new data pattern
contained in the instruction and the part is ready for a next instruction.
