Erase All
The Erase All Memory (ERAL) instruction erases
the whole memory (all memory bits are set to 1).
The format of the instruction requires that a dum-
my address be provided. The Erase cycle is con-
ducted in the same way as the Erase instruction
(ERASE). The completion of the cycle can be de-
tected by monitoring the Ready/Busy line, as de-
scribed in the
READY/BUSY STATUS
section.
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 ad-
dress be provided. As with the Write Data to Mem-
ory (WRITE) instruction, the format of the Write All
Memory with same Data (WRAL) instruction re-
quires that an 8-bit data byte, or 16-bit data word,
be provided. This value is written to all the ad-
dresses of the memory device. The completion of
the cycle can be detected by monitoring the
Ready/Busy line, as described next.
