3.8.4.3 Automatic Remote Loopback
nel is configured into the Automatic Remote Loopback mode. In this mode,
if the Activate Loopback Code has been detected in the receive data for
more than 5.1 s, the Remote Loopback (shown as Figure-16) will be estab-
lished automatically, and the RLP_S bit (STAT1, 17H...) will be set to ‘1’ to
indicate the establishment of the Remote Loopback. The IBLBA_S bit
(STAT0, 16H...) is set to ‘1’ to generate an interrupt. In this case, the Remote
