SATURN USER NETWORK INTERFACE
LLE:
The LLE bit enables the S/UNI line loopback. Line loopback may only be
activated while the bit serial interface is selected (TSER and RSER are both
tied high). When LLE is a logic one, RXD+, RXD-, RXC+, and RXC- are
connected internally to TXD+, TXD-, TXCO+, and TXCO- respectively.
TPFERF:
The TPFERF bit forces the S/UNI to transmit PATH FERF. When TPFERF is
set to logic one, Path FERF is transmitted by setting the Path Status (G1)
byte's FEBE field to 1001 binary. When TPFERF is set to logic zero, the G1
byte's FEBE field is inserted by the TPOP block.
PFERFV:
The PFERFV bit reflects the current Path FERF state. When logic one, the
S/UNI is currently detecting Path FERF in the receive stream. When logic
zero, Path FERF is not detected in the receive stream.
PFERFE:
The PFERFE bit enables the S/UNI Path FERF interrupt. When logic one, the
S/UNI INTB output is asserted when there is a change in the Path FERF
state. When logic zero, the S/UNI INTB output is not affected by the change in
Path FERF states.
