Status byte - bit description
Slicer control - bit description
9.3.19 Subaddress 1Fh (read only register)
9.3.20 Subaddress 40h
Description
status bit for interlace detection
status bit for locked horizontal frequency (OLDSB = 1)
status bit for horizontal/vertical loop (OLDSB = 0)
identification bit for detected field frequency
gain value for active luminance channel is limited [max (top)]; active HIGH
gain value for active luminance channel is limited [min (bottom)]; active HIGH
white peak loop is activated; active HIGH
slow time constant active in WIPA mode; active HIGH (OLDSB = 1)
Macrovision
revision 7.01 (OLDSB = 0).
color signal in accordance with selected standard has been detected; active HIGH (OLDSB = 1)
ready for capture (all internal loops locked); active HIGH (OLDSB = 0)
Description
field size select
hamming check
framing code error
amplitude searching
not used; has to be set to logic 0
0 = non-interlaced
1 = interlaced
0 = locked
1 = unlocked
0 = locked
1 = unlocked
0 = 50 Hz
1 = 60 Hz
0 = 50 Hz field rate
1 = 60 Hz field rate
0 = hamming check for 2 bytes after framing code, dependent on data type (default)
1 = no hamming check
0 = one framing code error allowed
1 = no framing code errors allowed
0 = amplitude searching active (default)
1 = amplitude searching stopped
