Section 11 Local Bus State Controller (LBSC)
The MPX interface timing is shown below.
When the MPX interface is used for areas 1, 2, and 4 to 6, a bus size of 32 bits should be specified
by CSnBCR.
In wait control, either waits by CSnWCR or waits by the RDY pin can be inserted.
In a read, one wait cycle is automatically inserted after address output, even if CSnWCR is cleared
to 0.
