13. Bus State Controller (BSC)
Bits 14 and 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 14: A1MPX
0

Description
SRAM/byte control SRAM interface is selected for area 1
MPX interface is selected for area 1
(Initial value)
Bit 13: A4MPX
0
1
Description
SRAM/byte control SRAM interface is selected for area 4
MPX interface is selected for area 4
(Initial value)
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.
