Table20-1.InstructionSetSummary(continued)
Note1: The active accumulator (Acc) is not allowed as the src in operations where it is the implicit destination .
Note2: 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 .
Note3: The terms Acc and A[AP] can be used interchangeably to denote the active accumulator .
Note4: Any index represented by or found inside [ ] brackets is considered variable, but required .
Note5: The active accumulator (Acc) is not allowed as the dst if A[AP] is specified as the src .
Note6: The ‘{L/S}’ prefix is optional .
Note7: 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 .
Note8: Special cases: If ‘MOVE APC, Acc’ sets the APC .CLR bit, AP will be cleared, overriding any auto-inc/dec/modulo opera-
tion specified for AP . If ‘MOVE AP, Acc’ causes an auto-inc/dec/modulo operation on AP, this overrides the specified data
transfer (i .e ., Acc will not be transferred to AP) .
