DLOOP
Digital Loopback
Digital loopback allows the Transmit input pins to be looped back
to the Receive output pins for local diagnostics. The Transmit
serial output data is valid during the digital loopback.
"0" = Disabled
"1" = Enable DLOOP

D1
RLOOPS
Serial Remote Loopback
Serial remote loopback allows the Receive serial input pins to be
looped back to the Transmit serial output pins for remote diagnos-
tics. The Receive output data is valid during a serial remote loop-
back.
"0" = Disabled
"1" = Enable RLOOPS

RLOOPP
Parallel Remote Loopback
Parallel remote loopback has the same affect as the serial remote
loopback, except that the input data is allowed to pass through the
SIPO before it’s looped back to the Transmit path, wherein it
passes through the Transmit FIFO, through the PISO, and back
out the Transmit serial output. The Receive output data is valid
during a serial remote loopback.
"0" = Disabled
"1" = Enable RLOOPP
