Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Operation when a value other than 0 is written is not
guaranteed.
Memory Configuration Select Bits
These bits select the memory configuration to be used.
These are used in combination with the BASFT and the
BWIDTH bits. For details on address multiplexing, refer
to section 12.5.6, Regarding Address Multiplexing.
