The Reserved bit must be set to a logic zero.
The T82R8LOOP bit enables a diagnostic loopback from the transmit 8B/10B encoded bus to
the receive 8B/10B encoded bus. When T82R8LOOP is a logic one, the entire SBI336 or
TelecomBus is looped back from the output of the TW8E and TP8E to the input of the RW8D
and RP8D, respectively. When T82R8LOOP is a logic zero, no loopback is performed.
The T2RLOOP bit enables a diagnostic loopback from the transmit interface to the receive
interface. When T2RLOOP is a logic one, the entire SBI336 or TelecomBus is looped back
from the output of the ICASM to the input of the OCASE. When T2RLOOP is a logic zero,
no loopback is performed.
