Conditional
Branching
The 8051
contains
a suite
of
instructions
which,
as a
group,
are
referred
to as
"conditional
branching"
instructions.
These
instructions
cause
program
execution
to
follow a
non-sequential
path if
a
certain
condition
is true.
Take,
for
example,
the JB
instruction.
This
instruction
means
"Jump if
Bit
Set." An
example
of the
JB
instruction
might
be:
|
|
JB 45h,HELLO |
|
|
NOP |
|
HELLO: |
.... |
