Section 13 Bus State Controller (BSC)
Bits 8 and 7—Memory Data Size (SZ1, SZ0): These bits specify the bus width of DRAM and
synchronous DRAM. This setting has priority over the BCR2 register setting.
Bit 8: SZ1

1
Bits 6 to 3—Address Multiplexing (AMXEXT, AMX2–AMX0): These bits specify address
multiplexing for DRAM and synchronous DRAM. The address shift value is different for the
DRAM interface and the synchronous DRAM interface.
• For DRAM Interface:
