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

Reserved

Horizontal per vertical tolerance, +/- 2n

Refer to register 0x0111

Reserved

Toggle on activity status update in Free-

running mode. No function in one-shot

mode.
