K2[7:0]:
TLOP Transmit K2
The K2[7:0] bits contain the value inserted in the K2 byte when the APSREG bit in the
TLOP Control Register is logic one. K2[7] is the most significant bit corresponding to bit
1, the first bit transmitted. K2[0] is the least significant bit, corresponding to bit 8, the last
bit transmitted. The bits in this register are double buffered so that register writes do not
need to be synchronized to SONET/SDH frame boundaries. The insertion of a new APS
code value is initiated by a write to the TLOP Transmit K1 Register. A coherent APS code
value is ensured by writing the desired K2 APS code value to this register before writing the
TLOP Transmit K1 Register.
