RPLDMV
The receive payload type label mismatch status bit (RPLDMV) reports the match/mismatch
status between the expected and the received payload type label. RPLDMV is set high when
the received payload type bits differ from the expected payload type written to the TTB
Expected Payload Type Label Register. The PLDMV bit is set low when the received payload
type matches the expected payload type.
RPLDMI
The receive payload type label mismatch interrupt status bit (RPLDMI) is set high when the
match/mismatch status between the received and the expected payload type label changes
state. This bit (and the interrupt) is cleared when this register is read.
RPLDUV
The receive payload type label unstable status bit (RPLDUV) reports the stable/unstable
status of the payload type label bits in the receive stream. RPLDUV is set high when five
labels that differ from its immediate predecessor are received. RPLDUV is set low and the
unstable label count is reset when five consecutive identical labels are received.
RPLDUI
The receive payload type label unstable interrupt status bit (RPLDUI) is set high when the
stable/unstable status of the path signal label changes state. This bit (and the interrupt) is
cleared when this register is read.
