11. Local Bus State Controller (LBSC)
The MPX interface timing is shown below.
When the MPX interface is used for area 0, the bus size should be set to 64 or 32 bits by MODE5
and MODE6. When the MPX interface is used for areas 1 to 6, the bus size should be set to 32 or
64 bits by CSnBCR.
Waits can be inserted by CSnWCR and the RDY pin.
In reading, one wait cycle is automatically inserted after address output even if CSnWCR is
cleared to 0.
