SUBB A, Source
This instruction subtracts the source byte and the carry
(borrow) flag from the accumulator. It references the carry
(borrow) status flag.
Table 69. SUBB A (Source) Affected Status Flags
Flag
C
OV
AC
MUL AB
This instruction multiplies the accumulator by the B SFR. This
operation is unsigned. The lower byte of the 16-bit product is
stored in the accumulator and the higher byte is left in the B
register. No status flags are referenced by the instruction.
Table 70. MUL AB Affected Status Flags
Flag
C
OV
DIV AB
This instruction divides the accumulator by the B SFR. This
operation is unsigned. The integer part of the quotient is stored
in the accumulator and the remainder goes into the B register.
No status flags are referenced by the instruction.
Table 71. DIV AB Affected Status Flags
Flag
C
OV
DA A
This instruction adjusts the accumulator to hold two 4-bit digits
after the addition of two binary coded decimals (BCDs) with
the ADD or ADDC instructions. If the AC bit is set or if the value
of Bit 0 to Bit 3 exceeds 9, 0x06 is added to the accumulator
Description
Set if there is a borrow needed for Bit 7. Cleared
otherwise. Used to indicate an overflow if the
operands are unsigned.
Set if there is a borrow needed for Bit 6 or Bit 7, but
not for both. Used to indicate an overflow for signed
subtraction. This flag is set if a negative number
subtracted from a positive number yields a negative
result or if a positive number subtracted from a
negative number yields a positive result.
Set if a borrow is needed for Bit 3. Cleared otherwise.
Description
Cleared
Cleared unless the B register is equal to 0, in which
case the results of the division are undefined and the
OV flag is set.
Description
Cleared
Set if the result is greater than 255. Cleared otherwise.

to correct the lower four bits. If the carry bit is set when the
instruction begins, or if 0x06 is added to the accumulator in the
first step, 0x60 is added to the accumulator to correct the higher
four bits.
The carry and AC status flags are referenced by this instruction.
Table 72. DA A Affected Status Flag
Flag
C
RRC A
This instruction rotates the accumulator to the right through
the carry flag. The old LSB of the accumulator becomes the new
carry flag, and the old carry flag is loaded into the new MSB of
the accumulator.
The carry status flag is referenced by this instruction.
Table 73. RRC A Affected Status Flag
Flag
C
RLC A
This instruction rotates the accumulator to the left through the
carry flag. The old MSB of the accumulator becomes the new
carry flag, and the old carry flag is loaded into the new LSB of
the accumulator.
The carry status flag is referenced by this instruction.
Table 74. RLC A Affected Status Flag
Flag
C
CJNE Destination, Source, Relative Jump
This instruction compares the source value to the destination
value and branches to the location set by the relative jump if
they are not equal. If the values are equal, program execution
continues with the instruction after the CJNE instruction.
No status flags are referenced by this instruction.
Table 75. CJNE Destination (Source, Relative Jump) Affected
Status Flags
Flag
C
Description
Set if the source value is greater than the destination
value. Cleared otherwise.
Description
Equal to the state of ACC[7] before execution of the
instruction.
Description
Set if the result is greater than 0x99. Cleared
otherwise.
Description
Equal to the state of ACC[0] before execution of the
instruction.
