Bit 15
A1MPX/A4MPX Enable (MEMMODE): Determines whether or not the selection of
either the MPX interface or the SRAM interface is by A1MPX and A4MPX rather than by
MEMMPX.
Bit 15: MEMMODE

Bits 14, 13
MPX-Interface Specification for Area 1 and 4 (A1MPX, A4MPX): These bits
specify the types of memory connected to areas 1 and 4. These settings are validated by
MEMMODE.

Bit 0
Burst Length (SDBL): Sets the burst length when the synchronous DRAM interface is
used. The burst-length setting is only valid when the bus width is 32 bits.
