STATUS SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to indicate the portion of the video line containing active video data.
H signal timing is configurable via the H_CONFIG bit of the
IOPROC_DISABLE register accessible via the host interface.
Active Line Blanking (H_CONFIG = 0
h
)
The H signal will be HIGH for the entire horizontal blanking period,
including the EAV and SAV TRS words, and LOW otherwise. This is the
default setting.
TRS Based Blanking (H_CONFIG = 1
h
)
The H signal will be HIGH for the entire horizontal blanking period as
indicated by the H bit in the received TRS ID words, and LOW otherwise.
