This register controls line loopback for tributaries #21 to #28 of SPE #2 and
tributaries #1 to #8 of SPE #3.
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.
