2.9
The Write All (WRAL) instruction will write the entire
memory array with the data specified in the command.
The self-timed auto-erase and programming cycle is
initiated by the rising edge of CLK on the last data bit.
Clocking of the CLK pin is not necessary after the
device has entered the WRAL cycle. The WRAL
command includes an automatic ERAL cycle for the
device, so the WRAL instruction does not require an
ERAL instruction. However, the chip must be in the
EWEN status.
