Activate internal modem control loopback function. This
internal loopback only affects the hardware handshake
signals. Use the UART1Ctrl LBE bit to loopback the serial
data.
When high, modem control outputs RTSn and DTRn are
forced high (inactive), and modem control inputs are
driven by outputs:
DSR = DTR
CTS = RTS
RI2 = OUT1
DCD = OUT2
OUT2 function. Used for internal loopback.
OUT1 function. Used for internal loopback.
RTS output signal:
1 - RTSn pin low
0 - RTSn pin high
DTR output signal:
1 - DTRn pin low
0 - DTRn pin high
