Bit 5—Memory Data Size (SZ): Specifies the memory data bus size for DRAM, synchronous
DRAM, and pseudo-SRAM. Always set this bit to 1 when synchronous DRAM is used. Takes
precedence over the BCR2 register designation.
Bit 5: SZ

Bits 4 and 3—Address Multiplex (AMX1, AMX0): These bits specify address multiplexing for
DRAM and synchronous DRAM. The actual address shift value differs between DRAM interface
and synchronous DRAM interface.
For DRAM Interface:
Bit 4: AMX1

Bit 2—Refresh Control (RFSH): Determines whether or not refreshing of DRAM, synchronous
DRAM, and pseudo-SRAM is performed. The timer for generation of the refresh request
frequency can also be used as an interval timer.
