Description In the direct addressing mode, the MAR instruction acts as a NOP instruction.
In the indirect addressing mode, an auxiliary register value and the ARP value
can be modified; however, the memory being referenced is not used. When
MAR modifies the ARP value, the old ARP value is copied to the ARB field of
ST1. Any operation that MAR performs with indirect addressing can also be
performed with any instruction that supports indirect addressing. In addition,
the ARP can also be loaded by an LST instruction.
The LARP instruction from the ’C25 instruction set is a subset of MAR. For ex-
ample, MAR *, AR4 performs the same function as LARP 4, which loads the
ARP with 4.
For loading an auxiliary register, see the description for the LAR instruction.
For storing an auxiliary register value to data memory, see the SAR instruction.
