4.7.4 HVF Timing Signal Generation
The GS1559 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 Error Correction and Insertion on page 53).
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 4-3.
