The external pin for specifying endian (MD5) is sampled on power-on reset. When big
endian is specified, this bit is read as 0 and when little endian is specified, this bit is
read as 1.

Endian Flag
Samples the external pin for specifying endian on power-on
reset (MD5) and specifies the pin value as the initial value.
All address spaces are defined by this bit. This is a read-only
bit.
0: The external pin for specifying endian (MD5) was low level
1: The external pin for specifying endian (MD5) was high
Reserved
This bit is always read as 0. The write value should always
be 0. If 1 is written to this bit, correct operation cannot be
guaranteed.
Specifies the pin state in standby mode for A23 to A0, BS,
CSn, RD/WR, WEn/DQMn, and RD.
0: High impedance in standby mode.
1: Driven in standby mode
Specifies the state in standby mode and bus released for
CKIO, CKE, RAS, and CAS.
