Load the contents of the addressed data-memory lo-
cation into T register (TMS320C1x/2x/2xx) or TREG0
(TMS320C5x) and add the contents of the P register
to the accumulator.

Load the contents of the addressed data-memory lo-
cation into the T register (TMS320C1x/2x/2xx) or
TREG0 (TMS320C5x), add the contents of the P regis-
ter to the accumulator, and copy the contents of the
specified location into the next higher address (both
data-memory locations must reside in on-chip data
RAM).

Load T Register, Subtract Previous Product
Load the contents of the addressed data-memory lo-
cation into the T register (TMS320C1x/2x/2xx) or
TREG0 (TMS320C5x). Shift the contents of the prod-
uct register as specified by the PM status bits, and sub-
tract the result from the accumulator.
