Table 19-1. MAXQ7667 Instruction Set Summary (continued)

Note 1: The active accumulator (Acc) is not allowed as the src in operations where it is the implicit destination.

Note 2: Only module 8 and modules 0-5 (when implemented for a given product) are supported by these single-cycle bit operations.

Potentially affects C or E if PSF register is the destination. Potentially affects S and/or Z if AP or APC is the destination.

Note 3: The terms Acc and A[AP] can be used interchangeably to denote the active accumulator.

Note 4: Any index represented by <b> or found inside [ ] brackets is considered variable, but required.

Note 5: The active accumulator (Acc) is not allowed as the dst if A[AP] is specified as the src.

Note 6: The '{L/S}' prefix is optional.

Note 7: Instructions that attempt to simultaneously push/pop the stack (e.g. PUSH @SP--, PUSH @SPI--, POP @++SP, POPI @++SP)

or modify SP in a conflicting manner (e.g., MOVE SP, @SP--) are invalid.

Note 8: Special cases: If ‘MOVE APC, Acc’ sets the APC.CLR bit, AP will be cleared, overriding any autoinc/dec/modulo operation

specified for AP. If ‘MOVE AP, Acc’ causes an autoinc/dec/modulo operation on AP, this overrides the specified data transfer

(i.e., Acc will not be transferred to AP).
