1.8 Accumulator A and Accumulator B

Accumulator A (ACCA) and Accumulator B (ACCB) are 72-bit wide registers utilized by DSP instructions to perform mathematical and shifting operations.

Accumulator A and Accumulator B can also be used as destination registers in MCU MUL.xx instructions. This helps reduce the execution time of extended precision arithmetic operations.

Refer to Figure 3-13 for details on using ACCA and ACCB.
