External Interface Write Timing - Normal Mode
The following sections describe the external interface timing.

performing a Write operation. In
generator is configured to provide 1 Wait state during Write operations. The external
WAIT input pin is generating an additional Wait period. Also in
assumed that the chip select (CS) signal has been configured for active Low operation.
Though the internal system clock is not provided as an external signal, it provides a useful
reference for control signal events. Note that at the completion of a Write cycle, the
de-assertion of the WR signal is fed back from the pin and used on chip to control the 
de-assertion of the data, CS, address and byte enable signals to assure proper timing of the
data hold.
