0RWBR7
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Endian Control
This field is used to program the endian configuration. The encodings
below are with respect to an input word = (B3, B2, B1, B0)
Refer to Table 12-1 on page 947 for more information regarding endian
configuration and control.
DescriptionValue
Configuration unchanged. (B3, B2, B1, B0)0x0
Bytes are swapped in half-words but half-words are not swapped
(B2, B3, B0, B1)
0x1
Half-words are swapped but bytes are not swapped in half-word.
(B1, B0, B3, B2)
0x2
