C.4.9
The TCS compiler supports the loading of instruction in
memory differently for Big Endian and Little Endian
modes.
C.5
TM1300 is required to operate in the same endian-ness
as the host CPU. At reset, TM1300 operates in Big Endi-
an mode; no special steps are required to set the Endian
bits. When using TM1300 in Little Endian systems, the
