LBON
This
bit
provides
a
local
loopback
feature
for
diagnostic
testing
of
the
UART.
When
bit
4
is
set
to
ë1í,
the
transmitter
Serial
Output
(SOUT)
is
set
to
the
Marking
(logic
1)
state.
The
receiver
Serial
Input
(SIN)
is
disconnected;
the
output
of
the
Transmitter
Shift
Register
is
ìlooped
backî
into
the
Receiver
Shift
Register
input.
The
two
flow
control
outputs
(nDTR
and
nRTS).
On
the
diagnostic
mode,
the
transmitted
data
is
immediately
received.
This
feature
allows
the
processor
to
verify
the
transmit-
and
received-data
paths
of
the
UART.
In
the
diagnostic
mode,
the
receiver
and
transmitter
interrupts
are
fully
operational.
