Bits 6 to 3—Address Multiplex (AMX3, AMX2, AMX1, AMX0): Specify address multiplexing
for synchronous DRAM.
For Synchronous DRAM Interface:
Notes: 1. Can only be set when using a 16-bit bus width.
Bit 2—Refresh Control (RFSH): The RFSH bit determines whether or not synchronous DRAM
refresh operations are is performed. If the refresh function is not used, the timer for generation of
periodic refresh requests can also be used as an interval timer.
