Performance Monitoring Registers
5-63
5.13 Performance Monitoring Registers
These registers contain the aggregated statistical and monitoring
information made available to the OBC block.
5.13.1 Performance Monitoring Register 1 (0x32)
This is a 7-bit wide, read/write register.
S3
Stage 3 Synchro Flag
D6 R
S3 is set when the descrambler synchronization acquires
synchronization.
The initial value of S3 is 0.
S2
Stage 2 Synchro Flag
D5 R
S2 is set when the deinterleaver/Reed-Solomon decoder
synchronization acquires synchronization.
The initial value of S2 is 0.
START_SYNC_OK
FFT Synchro
D4 R
If the start FFT window synchronization in the DTTV
demodulator is OK, this bit is 1.
The initial value of START_SYNC_OK is 0.
