7 Carrier Found Flag
When the Carrier Found (CF) flag (see Chapter 4.4 on page 14) is
set, it indicates that a QPSK signal is present at the input of the Viterbi
decoder.
[6:5] Not relevant.
4 Puncture Rate Found
The Puncture Rate Found (PRF) bit indicates the state of the punc-
ture rate research: 0 for searching and 1 when found. This bit is irrele-
vant in manual mode.
3 Locked/Searching Sync Word
The LK bit indicates the state of the sync word search: 0 for searching
and 1 when found.
[2:0] Current Puncture Rate, PR[2:0]
The Current Puncture Rate (CPR) bits hold the current puncture rate
indices, as follows:
100: Basic 1/2 (modes DVB and DSS) or Punctured 1/2 (reserved
mode)
000: Punctured 2/3
001: Punctured 3/4
010: Punctured 5/6
011: Punctured 7/8 (modes DVB and DSS) or 6/7 (reserved mode)
