Reserved
Number of lines to skip before starting a
horizontal measurement. The skip counter
counts from the chosen vertical source and
edge. [11:8]
Reserved
1 = delay vsync a number of XCLKs
specified in SMEAS_DELAY_VSYNC
Reserved
Write a rising edge to start the hv-skew
measurement.
Test skew limit in XCLKs. If the skew is less
than this test limit, the
SMEASE_SKEW_STATUS register will
report an error condition.
SMEAS_DELAY_VSYNC should be
reprogrammed until the skew is large
enough to prevent vcount ambiguity.
Number of XCLKs to delay vsync.
Reference value for XCLKs per horizontal
event
actual value = programmed value + 1
Reference value for XCLKs per vertical
event
actual value = programmed value + 2
Reference value for horizontal events per
vertical event
Reference value for vertical pulse width
measurement result in XCLKs.
actual value = programmed value + 1
Reserved
Reference value for Hsync polarity.
0: active low
1: active high
Reference value for Vsync polarity.
0: active low
1: active high
Reserved
Horizontal tolerance; ± 2n XCLKs
Reserved
Vertical tolerance; ± 2n XCLKs
