Write is the logic function of GW, BWE, BW1, BW2. See Byte Write Function table for detail.
All inputs, except OE, must meet setup and hold on rising edge of CLK.
Suspending busrt generates a wait cycle.
ADSP LOW along with SRAM being selected always initiates a Read cycle at the L-H edge of the clock (CLK).
A Write cycle can only be performed by setting Write low for the clock L-H edge of the subsequent wait cycle.
Refer to
page 12
for the Write timing diagram.
