Write All
As with the Erase All Memory (ERAL) instruction, the format of the Write All Memory with
same Data (WRAL) instruction requires that a dummy address be provided. As with the
Write Data to Memory (WRITE) instruction, the format of the Write All Memory with same
Data (WRAL) instruction requires that an 8-bit data byte, or 16-bit data word, be provided.
This value is written to all the addresses of the memory device. The completion of the cycle
can be detected by monitoring the READY/BUSY line, as described next.
