K1[7:0]:
The K1[7:0] bits contain the value inserted in the K1 byte when the APSREG bit in the TLOP
Control Register is logic one. K1[7] is the most significant bit corresponding to bit 1, the first
bit transmitted. K1[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 this register. The contents of this register, and the TLOP Transmit K2
Register are inserted in the SONET/SDH stream starting at the next frame boundary.
Successive writes to this register must be spaced at least two frames (250 µs) apart.
