Table 53. Indirect-Addressing Instruction Bit Summary Single Data-MemoryOperand (Continued)CMPT = 1 Compatibility mode. In compatibility mode, ARP selects the auxiliary registerif ARF = 0. Otherwise, ARF selects the auxiliary register and the ARF valueis loaded into ARP when the access is completed. *AR0 in the assemblyinstruction indicates the auxiliary register selected by ARP in compatibilitymode.
