Logical instructions
Table 5
Boolean operations (AND, OR, Exclusive OR, NOT) on bytes perform the operation on a bit-
by-bit basis. That is, if the Accumulator contains 00110101B and byte contains 01010011B,
then:
will leave the Accumulator holding 00010001B.
The addressing modes that can be used to access the <byte> operand are listed in
The ANL A, <byte> instruction may take any of the forms:
Boolean operations can be performed on any byte in the internal Data Memory space
without going through the Accumulator. The XRL <byte>, #data instruction, for example,
offers a quick and easy way to invert port bits, as in:
If the operation is in response to an interrupt, not using the Accumulator saves the time and
effort to push it onto the stack in the service routine.
The Rotate instructions (RL A, RLC A, etc.) shift the Accumulator 1 bit to the left or right. For
a left rotation, the MSB rolls into the LSB position. For a right rotation, the LSB rolls into the
MSB position.
The SWAP A instruction interchanges the high and low nibbles within the Accumulator. This
is a useful operation in BCD manipulations. For example, if the Accumulator contains a
ANL A, <byte>
ANL A,7FH(direct addressing)
ANL A, @R1 (indirect addressing)
ANL A,R6 (register addressing)
ANL A,#53H (immediate constant)
XRL P1, #0FFH.
