Double indirect addressing mode with pointer post-modification.
Parallel Data Move allows one operand move during Multiply-Accumulate instructions
without penalty.
CoSTORE instruction (for fast access to the MAC SFRs) and CoMOV (for fast memory to
memory table transfer).
Two-cycle execution for all MAC operations.
16 x 16 signed/unsigned parallel multiplier.
40-bit signed arithmetic unit with automatic saturation mode.
40-bit accumulator.
8-bit left/right shifter.
Scaler (one-bit left shifter)
Data limiter
Full instruction set with multiply and multiply-accumulate, 32-bit signed arithmetic and
compare instructions.
Three 16-bit status and control registers: MSW: MAC Status Word, MCW: MAC Control
Word, MRW: MAC Repeat Word.
Repeat Unit allows some MAC co-processor instructions to be repeated up to 8192 times.
Repeated instructions may be interrupted.
MAC interrupt (Class B Trap) on MAC condition flags.
