READ-MODIFY-WRITE INSTRUCTIONS
Some 8052 instructions read the latch and others read the pin.
The state of the pin is read for instructions that input a port bit.
Instructions that read the latch rather than the pins are the ones
that read a value, possibly change it, and rewrite it to the latch.
Because these instructions involve modifying the port, it is
assumed that the pins being modified are outputs, so the output
state of the pin is read from the latch. This prevents a possible
misinterpretation of the voltage level of a pin. For example, if a
INSTRUCTIONS THAT AFFECT FLAGS
Many instructions explicitly modify the carry bit, such as the
MOV C bit and CLR C instructions. Other instructions that
affect status flags are listed in this section.
ADD A, Source
This instruction adds the source to the accumulator. No status
flags are referenced by the instruction.
Table 67. ADD A (Source) Affected Status Flags
port pin is used to drive the base of a transistor, a 1 is written to
the bit to turn on the transistor. If the CPU reads the same port
bit at the pin rather than the latch, it reads the base voltage of
the transistor and interprets it as Logic 0. Reading the latch
rather than the pin returns the correct value of 1.
The instructions that read the latch rather than the pins are
called read-modify-write instructions and are listed in Table 66.
When the destination operand is a port or a port bit, these
instructions read the latch rather than the pin.

Description
Set if there is a carry out of Bit 7. Cleared otherwise.
Used to indicate an overflow if the operands are
unsigned.
Set if there is a carry out of Bit 6 or a carry out of Bit 7,
but not if both are set. Used to indicate an overflow for
signed addition. This flag is set if two positive operands
yield a negative result or if two negative operands yield
a positive result.
Set if there is a carry out of Bit 3. Cleared otherwise.

This instruction adds the source and the carry bit to the accu-
mulator. The carry status flag is referenced by the instruction.

Flag Description
C Set if there is a carry out of Bit 7. Cleared otherwise.
Used to indicate an overflow if the operands are
unsigned.
OV Set if there is a carry out of Bit 6 or a carry out of Bit 7, but
not if both are set. Used to indicate an overflow for
signed addition. This flag is set if two positive operands
yield a negative result or if two negative operands yield
1
These instructions read the port byte (all eight bits), modify the addressed
bit, and write the new byte back to the latch.
AC
a positive result.
Set if there is a carry out of Bit 3. Cleared otherwise.
