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 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.
