In the fi rst four instruction types, it is in the accumulator that the fi nal result would be available. However,
in the last two instruction types, it is the directly addressed memory location which would store the fi nal result
of the AND operation.
e execution of instruction ANL A, B is illustrated as an example case in Fig. 9.1. Assuming original
contents of the registers A and B to be 57H and A9H, respectively, after the AND operation, the accumulator
would have 01H as the result. No fl ags would be aff ected. Note that this is a 2-byte instruction indicated by
the opcode 55H. Direct address of the SFR B (F0H) becomes ...
