Stage 1 Synchronization Flag
The L64724 sets the S1_S bit when the Viterbi Decoder
synchronization module has acquired synchronization.
The L64724 also generates an interrupt if the S1_S_IE
bit is set in the SMR. The L64724 clears S1_S to 0 after
a reset or a Group 2 (STS) read.
Reserved
This bit is reserved for LSI Logic internal use only.
Reading this bit will give unpredictable results.
Timing Lock Established
The L64724 sets the CLK_LK bit when Timing Lock is
established.
Timing Lock Lost
The L64724 sets the CLK_LLK bit when Timing Lock is
lost.
