used to clear HF
0
and HF
1
during normal
operation (see HBLANK discussion).
HBLANK
HBLANK is used to replace portions of the
input data with user-defined blanking
levels. When HBLANK is LOW, blanking
level words are injected into the data
stream immediately after the Input LUT
section regardless of this section being
used or not. While HBLANK is LOW,
blanking level words are continually
injected into the datapath with user-
defined blanking words. Blanking words
are injected on the next rising clock edge
when HBLANK is LOW. In addition,
HBLANK clears flags HF
0
and HF
1
and
resets a 20-bit incrementing counter (0 -
1,048,575). If a HIGH to LOW transition
on HBLANK is detected on a rising edge of
clock, HF
0
and HF
1
are cleared and the
counter is reset on the following rising
edge of clock (see Figure 10). Key Channel
blanking may be independently enabled
or disabled using Congifuration Register 1
(see Table 6).
HF
0
/HF
1
and Counter
HF
0
and HF
1
are two independent flags
that are set when the pre-programmed
HF
0
or HF
1
count value is equal to the 20-
bit incrementing counter value. For each
flag, one user-defined 20-bit count value
can be programmed. When HF
0
or HF
1
count value is equal to the counter value,
HF
0
or HF
1
is set on the next rising edge
of clock. Once the flags are set, they must
be reset if they are needed again. The
counter will increment by one at the rate
of CLK and can be reset by HBLANK.
The counter will continue to loop if not
