WRITE Mode
The M48Z58/Y is in the WRITE Mode whenever W
and E are low. The start of a WRITE is referenced
from the latter occurring falling edge of W or E. A
WRITE is terminated by the earlier rising edge of
W or E. The addresses must be held valid through-
out the cycle. E or W must return high for a mini-
mum of t
