3.7.4 HVF Timing Signal Generation
The GS1560A extracts critical timing parameters from either
the received TRS signals (FW_EN/DIS = LOW), or from the
internal flywheel-timing generator (FW_EN/DIS = HIGH).
Horizontal blanking period (H), vertical blanking period (V),
and even / odd field (F) timing are all extracted and
presented to the application layer via the H:V:F status
output pins.
The H signal timing is configurable via the H_CONFIG bit of
the internal IOPROC_DISABLE register as either active line
based blanking, or TRS based blanking, (see Section
3.10.6).
Active line based blanking is enabled when the H_CONFIG
bit is set LOW. In this mode, the H output is HIGH for the
entire horizontal blanking period, including the EAV and
SAV TRS words. This is the default H timing used by the
device.
When H_CONFIG is set HIGH, TRS based blanking is
enabled. In this case, the H output will be HIGH for the
entire horizontal blanking period as indicated by the H bit in
the received TRS ID words.
The timing of these signals is shown in Figure 9.
