K2[7:0]:

The K2[7:0] bits contain the value inserted in the K2 byte when the APSREG bit in the TLOP Control Register is a logic one. K2[7] is the most significant bit, corresponding to the first bit (bit 1) transmitted. K2[0] is the least significant bit, corresponding to the last bit (bit 8) 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.
