This register controls line loopback for tributaries #1 to #16 of SPE #1.
SPE1_LBEN[16:1]:
The SPE #1 loopback enable bits (SPE1_LBEN[16:1]) control line loopback
for tributaries #16 to #1 of SPE #1 of the SBI Interface. When SPE1_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 SPE1_LBEN[n] is
set low, transmit data for tributary #n is provided by the TCAS block (i.e.
processed normally).
