This register controls line loopback for tributaries #9 to #24 of SPE #3.
SPE3_LBEN[24:9]:
The SPE #3 loopback enable bits (SPE3_LBEN[24:9]) control line loopback
for tributaries #24 to #9 of SPE #3 of the SBI Interface. When SPE3_LBEN[n]
is set high, the data on tributary #n output by the SBI PISO block is looped
back to the tributary #n input of the SBI SIPO block. When SPE3_LBEN[n] is
set low, transmit data for tributary #n is provided by the TCAS block (i.e.
processed normally).
