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 write sequence requires a logic high

edge of the last data bit.
After the Write cycle is complete, issuing a
Start bit and then taking CS low will clear
the Ready/Busy status from DO.
