The STRT value is the value of the horizontal down
counter at which the HSIGEN signal becomes active
(starts). This indicates the start of the signature calculation
for a horizontal line. HSIGEN is an internal block signal.
The SIG_ENABLE control to the video signature analyzer
is enabled by the logical AND of VSIGEN and HSIGEN.
Reserved. Unknown during read.
Vertical Clear - Read/Write
The VCLR value is the value of the Vertical down counter
at which the VSIGCLR signal is active. This indicates the
line for clearing the LFSR and storing the result value for
the Vertical frame. VSIGCLR is an internal block signal.
The SIG_CLR control to the video signature analyzer is
generated by the logical AND of VSIGCLR and HSIGCLR.
The SigClrStr control signal is also routed to an edge
trigger capable interrupt on the interrupt controller for use
as a programmable secondary raster engine interrupt
output.
Horizontal Clear - Read/Write
The HCLR value is the value of the Vertical down counter
at which the HSIGCLR signal is active. This indicates the
specific horizontal pixel clock for clearing the LFSR and
storing the result value within a horizontal line. HSIGCLR
is an internal block signal. The SIG_CLR control to the
video signature analyzer is generated by the logical AND
of VSIGCLR and HSIGCLR. The SigClrStr control signal is
also routed to an edge trigger capable interrupt on the
interrupt controller for use as a programmable secondary
raster engine interrupt output.
