Event handler triggers immediately after finishing a task
Event handler triggers with next V-sync
Event handler triggers with field ID = 0
Event handler triggers with field ID = 1
If active task is finished, handling is taken over by the next task
Active task is repeated once, before handling is taken over by the next task
SCALER INPUT FORMAT AND CONFIGURATION SOURCE
Only if XRQT[83H[2]] = 1: scaler input source reacts on
SAA7108E; SAA7109E request
Scaler input source is a continuous data stream, which cannot
be interrupted (must be logic 1 if SAA7108E; SAA7109E
decoder part is source of scaler or XRQT[83H[2]] = 0)
Scaler input source is data from decoder, data type is
provided according to Table 44
Scaler input source is Y-C
Scaler input source is raw digital CVBS from selected analog
channel, for backward compatibility only, further use is not
recommended
Scaler input source is raw digital CVBS (or 16-bit Y + C
no 16-bit output are active) from X port
SAV/EAV code bits 6 and 5 (F and V) may change between
SAV and EAV
SAV/EAV code bits 6 and 5 (F and V) are synchronized to
scalers output line start
SAV/EAV code bit 5 (V) and V gate on pin IGPV as generated
by the internal processing; see Fig.44
SAV/EAV code bit 5 (V) and V gate are inverted
