A write occurs during the overlap of a low CS and a low WE (t
t
During this period, I/O pins are in the output state. The input signals of the opposite
phase to the outputs must not be applied.
If CS is low during this period, I/O pins are in the output state. The data input signals of
opposite phase to the outputs must not be applied to them.
Dout is the same phase of write data of this write cycle.
WR
is measured from the earlier of CS or WE going high to the end of the write cycle.
