2.8
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.
