DRAFT(Thursday 20 June 2002, 13:15).
The MUL AB instruction multiplies the Accumula-
tor by the data in the B register and puts the 16-bit
product into the concatenated B and Accumulator
registers.
The DIV AB instructiondivides the Accumulator by
the data in the B register and leaves the 8-bit quo-
tient inthe Accumulator, and the 8-bit remainder in
the B register.
Oddly enough, DIV AB finds less use in arithmetic
“divide” routinesthan in radix conversionsand pro-
grammable shift operations. An example of the
use of DIV AB in a radix conversion will be given
later. In shift operations, dividing a number by 2n
shifts its n bits to the right. Using DIV AB to per-
form the division completes the shift in 4s and
leaves the B register holding the bits that were
shifted out. The DA A instruction is for BCD arith-
metic operations. In BCD arithmetic, ADD and
ADDC instructionsshould always be followed bya
DA A operation, to ensure that the result is also in
BCD. Note that DAA willnotconvert a binary num-
ber to BCD. The DA A operation produces a
meaningful result only as the second step in the
addition of two BCD bytes.

Logical Instructions
Table 5 shows list of
μ
PSD3200Family logical in-
structions. The instructions that perform 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:
ANL A, <byte>
will leave the Accumulator holding 00010001B.
The addressing modes that can be used to access
the <byte> operand are listed in Table 5.
The ANL A, <byte> instructionmay take any of the
forms:
ANL A,7FH(direct addressing)
ANL A, @R1 (indirect addressing)
ANL A,R6 (register addressing)
ANL A,#53H (immediate constant)
Note that Boolean operations canbe performedon
any byte in the internal Data Memory space with-
out going through the Accumulator. The XRL
<byte>, #data instruction, for example, offers a
quick and easy way to invert port bits, as in
XRL P1, #0FFH.
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
