Read-Modify-Write Instructions
Some 8051 instructions that read a port read the latch while
others read the pin. The instructions that read the latch rather
than the pins are the ones that read a value, possibly change it,
and then rewrite it to the latch. These are called read-modify-
write instructions, which are listed below. When the destination
operand is a port or a port bit, these instructions read the latch
rather than the pin.

INC

SETB PX.Y

1
These instructions read the port byte (all 8 bits), modify the addressed bit,
and then write the new byte back to the latch.
Read-modify-write instructions are directed to the latch rather
than to the pin to avoid a possible misinterpretation of the
voltage level of a pin. For example, a port pin might be used to
drive the base of a transistor. When 1 is written to the bit, the
transistor is turned on. If the CPU then reads the same port bit
at the pin rather than the latch, it reads the base voltage of the
transistor and interprets it as a Logic 0. Reading the latch rather
than the pin returns the correct value of 1.
