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 93AA46A/B/C and 93LC46A/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 93C46A/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:
Issuing a Start bit and then taking CS low
will clear the READY/BUSY status from
DO.
