Users Manual 305
In the case of write cycles, the chip select signals are active only around the trailing edge
of the write signal. Wait states are inserted between T1 and T2, and this will have no effect
on the duration of the chip select signals in this mode. The timing diagrams below illus-
trate the actual timing for the different divided cases. In these cases the chip selects are
active for two clock cycles before and two clock cycles after the trailing edge of the write
signal.
