2.11 Big-endian instruction support
The processor supports little-endian or big-endian instruction format, and is dependent on the
setting of the CFGIE pin. This is reflected in bit [31] of the System Control Register. For more
information, see c1, System Control Register on page 4-35.
Note
The facility to use big-endian or little-endian instruction format is an implementation option,
and you can therefore remove it in specific implementations. If this facility is not present, the
CFGIE pin is still reflected in the System Control Register but the instruction format is always
little-endian.
