3.15.1 MAC Operations

The mathematical operations performed by the MAC class of DSP instructions center around multiplying or squaring the contents of two Working registers and either adding, subtracting or storing the result to either Accumulator A or Accumulator B. This is the operation of the MAC, MPY, MPY.N, MSC, SQR, SQRAC, SQRSC and SQRN instructions.

For the ED and EDAC instructions, the same multiplicand operand must be specified by the instruction because this is the definition of the Euclidean Distance operation.
