Write mode
The M48T59/Y/V 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 throughout the cycle. E or W
must return high for a minimum of t
prior to the initiation of another READ or WRITE cycle. Data-in must be valid t
the end of WRITE and remain valid for t
WRITE cycles to avoid bus contention; however, if the output bus has been activated by a
low on E and G a low on W will disable the outputs t
