The Accumulator
If
you’ve
worked
with any
other
assembly
languages
you will
be
familiar
with the
concept
of an
Accumulator
register.
The
Accumulator,
as it’s
name
suggests,
is used
as a
general
register
to
accumulate
the
results
of a
large
number
of
instructions.
It can
hold an
8-bit
(1-byte)
value
and is
the most
versatile
register
the 8051
has due
to the
shear
number
of
instructions
that
make use
of the
accumulator.
More
than
half of
the
8051’s
255
instructions
manipulate
or use
the
accumulator
in some
way.
