In TU3 mode (TU3 bit in VTPP Configuration register set high), this register
reports the accepted path signal label of the TU3 mapped into a TUG3 handled
by the RTOP. Out of TU3 mode, this register reports the accepted path signal
label of TU #1 in TUG2 #1.
APSL[7:0]:
In TU3 mode, the APSL[7:0] bits report the accepted path signal label of the
TU3 stream. Out of TU3 mode, APSL[2:0] specifies the accepted path signal
label of tributary TU #1 in TUG2 #1. The expected PSL is compared with the
accepted PSL to determine the PSLM state.
