Bit 20—Area 4 SRAM Byte Control Mode (A4MBC): MPX interface has priority when an
MPX interface is set. This bit is initialized by a power-on reset.
Bit 20: A4MBC

1
Bit 19—BREQ Enable (BREQEN): Indicates whether external requests and bus requests from
PCIC can be accepted. BREQEN is initialized to the external request and bus request from PCIC
acceptance disabled state by a power-on reset. It is ignored in the case of a slave mode startup.
The bus request from the PCIC is always accepted in a slave mode start up.
Bit 19: BREQEN

1
Bit 17—Area 1 to 6 MPX Bus Specification (MEMMPX): Sets the MPX interface when areas 1
to 6 are set as SRAM interface (or burst ROM interface). MEMMPX is initialized by a power-on
reset.
Bit 17: MEMMPX
0
1
Bit 16—DMAC Burst Mode Transfer Priority Setting (DMABST): Specifies the priority of
burst mode transfers by the DMAC. When OFF, the priority is as follows: bus privilege released,
refresh, DMAC, CPU. When ON, the bus privileges are released and refresh operations are not
performed until the end of the DMAC's burst transfer. This bit is initialized at a power-on reset.
