Single
Board Computer
language
instructions
within
software prepared
for
specific
applications.
Output
is
latched
on
the
board,
so
that
after
an
OUT
instruction
is
executed,
the
eight
bits
of
data
remain
available
to
the
external
device
until
the
canputer
changes
it.
Input
is
N<Jl'
latched,
so
that
software must
be
written
to
sense
in
sane
way
that
data
is
available
and
to
input
that
data.
There
are
no
interrupt
lines
connected
to
the
parallel
ports.
