Description
Endian Flag
The value of the endian setting off-chip pin (MD5) is
sampled at a power-on reset by the RESET pin. This bit
determines the endian mode of all spaces.
0: Indicates that pin MD5 is low at a power-on reset and
1: Indicates that pin MD5 is high at a power-on reset and
Reserved
This bit is always read as 0. The write value should
always be 0.
Area 0 Memory Type
The value of the area 0 memory type setting off-chip pin
(MD6) is sampled at a power-on reset by the RESET pin.
This bit determines the memory type of area 0.
0: Indicates that pin MD6 is high and area 0 is specified
1: Indicates that pin MD6 is low, and area 0 is specified
Reserved
These bits are always read as 0. The write value should
always be 0.
