13.2.7 Multiplier Read Register 1 (MC1R)
Register Description:
Multiplier Read Register 1
Register Name:
MC1R
Register Address:
Module 001, Index 0Ch
Bits 15 to 0: Multiplier Read Register 1 Bits 15 to 0 (MC1R.15 to MC1R.0). The MC1R register represents bytes’ 3 and 2 result from
the last operation when MCW = 1 or the last operation was a multiply or multiply-negate. When MCW = 0 and the last operation was a
multiply-accumulate/subtract, the contents of this register may or may not agree with the contents of MC1 due to the combinatorial
nature of the adder. The contents of this register may change if MCNT, MA, MB, or MC2:MC0 is changed.
13.2.8 Multiplier Read Register 0 (MC0R)
Register Description:
Multiplier Read Register 0
Register Name:
MC0R
Register Address:
Module 001, Index 0Dh
Bits 15 to 0: Multiplier Read Register 0 Bits 15 to 0 (MC0R.15 to MC0R.0). The MC0R register represents bytes’ 1 and 0 result from
the last operation when MCW = 1 or the last operation was a multiply or multiply-negate. When MCW = 0 and the last operation was a
multiply-accumulate/subtract, the contents of this register may or may not agree with the contents of MC0 due to the combinatorial
nature of the adder. The contents of this register may change if MCNT, MA, MB, or MC2:MC0 is changed.
