4.2.2.2
The address of the operand is in the address register Rj or SP. After the operand address is used, it is
incremented by one and stored in the same address register. The type of arithmetic (linear or modulo) used
to increment Rn is determined by M01 for R0 and R1 and is always linear for R2, R3, and SP. The N
register is ignored. This reference is classified as a memory reference. See Figure 4-4.
