Figure 36. Timing Waveform of Write Cycle(2) (CS# controlled, if BYTE# is Low, Ignore UB#/LB# Timing)
Notes:
1. A write occurs during the overlap (t
WP
) of low CS1# and low WE#. A write begins when CS1# goes low and WE#
goes low with asserting UB# or LB# for single byte operation or simultaneously asserting UB# and LB# for double
byte operation. A write ends at the earliest transition when CS1# goes high and WE# goes high. The t
WP
is
measured from the beginning of write to the end of write.
2. t
CW
is measured from the CS1# going low to the end of write.
3. t
AS
is measured from the address valid to the beginning of write.
4. t
WR
is measured from the end of write to the address change. t
WR
applied in case a write ends as CS1# or WE#
going high.
