This automatically loads the
MAC32OV register.
The MACOV32 can generate a
MULT/ACCU interrupt when
enabled.

MULT/ACCU Unit Data Registers
The
operand and result registers that serve to store
the numbers being manipulated in mathematical
operations. Some of these registers are uniquely
for addition (such as MACC) while others can be
used for all operations. The MULT/ACCU
operation registers are represented below.
MACA and MACB Multiplication
(Addition) Input Registers
MULT/ACCU
Data
registers
include
The MACA and MACB register serve as 16-bit
input operands when performing multiplication.
When the MULT/ACCU is configured to perform
32-bit addition, the MACA and the MACB
registers are concatenated to represent a 32-bit
word. In that case the MACA register contains
the upper 16-bit of the 32-bit operand and the
MACB contains the lower 16-bit

The MACC register is a 32-bit register used to
perform 32-bit addition.
It’s possible to substitute the MACPREV
Register for the MACC register or 0 in the 32-bit
addition.
