Enhanced Multiply-Accumulate Unit (EMAC)
Executing this sequence type can correctly save and restore the exact state of the EMAC programming
model.
3.3.1.3
MULS and MULU are unaffected by fractional-mode operation; operands remain assumed to be integers.
3.3.1.4
The scale factor is ignored while the MAC is in fractional mode.
