Arguments: address and length
Effect: Canonicalize the scratchpad. Then scratchpad = scratchpad+operand
This command will cause an error if:
- The length is less than MAU_MIN_LENGTH or greater than MAU_MAX_LENGTH
- The scratchpad’s length is not equal to the operand’s length
- An arithmetic overflow occurs
- The memory address refers to a RAM or ROM slot, but those slots are not
configured
- The interval [address … address+length-1] does not all refer to the same type of
memory
