Figure 13.51 Example of 32-Bit Data Width MPX Connection
The MPX interface timing is shown below.
When the MPX interface is used for areas 1 to 6, a bus size of 32 bit should be specified in BCR2.
For wait control, waits specified by WCR2 and wait insertion by means of the RDY pin can be
used.
In a read, one wait cycle is automatically inserted after address output, even if WCR2 is cleared to
0.
