; Use integer numbers, and multiply only mode (add to zero)
; Load MAC0A register with 1234 hex = 4660 decimal
; Load MAC0B register with FEDC hex = -292 decimal
; This line initiates the Multiply operation
; After this instruction, the Accumulator should be equal to
; FFFFEB3CB0 hex = -1360720 decimal. The MAC0STA register should
; be 0x01, indicating a negative result.
; After this instruction, the Rounding register is updated
; The next few instructions load the accumulator with the value
; 4088442211 Hex.
; Initiate a Left-shift
; After this instruction, the accumulator should be 0x8110884422
; The rounding register is updated after this instruction
; Initiate a Right-shift
; Initiate a second Right-shift
; After this instruction, the accumulator should be 0xE044221108
; The rounding register is updated after this instruction
