Datasheet
Memory Controller
As illustrated in Figure 15-6, the timing of the CSx signal is the same as the timing of the
address lines. The strobes for the transaction are supplied by the OE or WEx signals,
depending on the transaction direction (read or write). The negation of the WEx signal is
controlled by the CSNT bit of the ORx register. The CSx signal is generated when the ACS
field in the corresponding ORx register is set to ‘00’.
