REJ09B0139-0400
Addressing
MACH, MACL
Mode
after execution of a MAC instruction. For example, if there is a one-state instruction (such as NOP)
between the MAC instruction and this instruction, this instruction will be two states longer.
The number of states may differ depending on the product. For details, refer to the relevant
microcontroller hardware manual of the product in question.
