This register controls line loopback for tributaries #5 to #20 of SPE #2.
Note
This register is not byte addressable. Writing to this register modifies all the bits
in the register. Byte selection using byte enable signals (CBEB[3:0]) are not
implemented. However, when all four byte enables are negated, no access is
made to this register.
SPE2_LBEN[20:5]:
The SPE #2 loopback enable bits (SPE2_LBEN[20:5]) control line loopback
for tributaries #20 to #5 of SPE #2 of the SBI Interface. When
