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
