2.8 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. For 93AA56A/B/C and 93LC56A/B/C
devices, after the last data bit is clocked into DI, the
falling edge of CS initiates the self-timed auto-erase and
programming cycle. For 93C56A/B/C devices, 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 (T CSL ). 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: After the Write cycle is complete, issuing a
Start bit and then taking CS low will clear
the Ready/ Busy status from DO.
