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 data output is valid during a serial remote loop-
back.
"0" = Enable Remote Serial Loopback
"1" = Disabled
N
OTE
:
DLOOP and RLOOPP should be
disabled
when RLOOPS
is enabled.

RLOOPP
Parallel Remote Loopback
Parallel remote loopback has the same affect as the serial remote
loopback, except that the data input 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 data output is valid during a
parallel remote loopback.
"0" = Enable Remote Parallel Loopback
"1" = Disabled
N
OTE
:
DLOOP and RLOOPS should be
disabled
when RLOOPP
is enabled. The internal FIFO should also be flushed using
FIFO_RST when parallel remote loopback is enabled/
disabled.
