This register controls line loopback for tributaries #21 to #28 of SPE #2 and
tributaries #1 to #8 of SPE #3.
SPE3_LBEN[28:21]:
The SPE #2 loopback enable bits (SPE2_LBEN[28:21]) control line loopback
for tributaries #28 to #21 of SPE #2 of the SBI Interface. When
SPE2_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
SPE2_LBEN[n] is set low, transmit data for tributary #n is provided by the
TCAS block (i.e. processed normally).
SPE3_LBEN[8:1]:
The SPE #3 loopback enable bits (SPE3_LBEN[8:1]) control line loopback for
tributaries #8 to #1 of SPE #3 of the SBI Interface. When SPE3_LBEN[n] is
