WRITE
The WRITE instruction is followed by 8 bits (If ORG is
low or A-version devices) or 16 bits (If ORG pin is high
or B-version devices) of data which are written into the
specified address. The self-timed auto-erase and
programming cycle is initiated by the rising edge of CLK
on the last data bit.
The DO pin indicates the READY/BUSY status of the
device, if CS is brought high after a minimum of 250 ns
low (TCSL). DO at logical ‘0’ indicates that programming
is still in progress. DO at logical ‘1’ indicates that the
register at the specified address has been written with
the data specified and the device is ready for another
instruction.
Note:
Issuing a Start bit and then taking CS low
will clear the READY/BUSY status from
DO.
