In TU3 mode (TU3 bit in VTPP Configuration register set high), this register
reports the status and configures operational modes of the TU3 mapped into a
TUG3 handled by the RTOP. Out of TU3 mode, this register reports the status
and configures the operational modes of TU #1 in TUG2 #1.
RDIE:
The RDIE bit enables the remote defect indication interrupt for tributary TU #1
in TUG2 #1 or TU3 depending on whether the RTOP is in TU3 mode. When
RDIE is set high, an interrupt is generated upon changes of RDI status.
Interrupts due to RDI status change are masked when RDIE is set low. The
RDI status is derived from bit 8 of the V5 byte when RDIZ7EN is set low and
from bits 5 to 7 of the Z7 byte when RDIZ7EN is set high.
RFIE:
The RFIE bit enables the remote failure indication interrupt for tributary TU #1
in TUG2 #1 or TU3 depending on whether the RTOP is in TU3 mode. When
RDIZ7EN is set low, an interrupt is generated upon assertion and negation
events of the RFIV bit when RFIE is set high. Interrupts due to RFIV status
change are masked when RFIE is set low. When RDIZ7EN is set high, RFIE
