Programmable Horizontal Blank
The leading edge position of the internal horizontal blank can
be programmed with respect to the horizontal flyback zero
crossing leading edge in steps of 4 OSD pixels up to a
maximum of 16 steps as shown below in
Figure 12
. This
start position of the horizontal blanking pulse is only pro-
grammable to occur before the horizontal flyback zero cross-
ing edge, and cannot be programmed in the opposite direc-
tion. The trailing edge of the horizontal blanking pulse is
independent of the programmable leading edge, and its
relativity to the Horizontal flyback trailing edge remains un-
changed. To use this feature, Horizontal Blanking (0x843A[0]
which is enabled by default) and Programmable Horizontal
Blanking (0x843A[2]) must be enabled. The number of steps
is programmed with the bits in 0x843A[6:3]. When this fea-
ture is disabled, please refer to the H-Blank Time Delay - On
specification (+ Zero Crossing of I
to 50% of output
blanking end) listed under the System Interface Signal Char-
acteristic section.
