R
[1] 0x0
Indicates that the horizontal measurement
timed out.
R
[0] 0x0
Indicates that the vertical measurement
timed out.
R
[7] 0x0
In Free-running mode any of the status bits
can change at the end of each
measurement. In One-shot mode any of the
status bits can change at the completion of
the measurement. The meas_sticky_status
bit is a bitwise OR of bits[3:0] (before the
bitwise OR, the mask in
SMEAS_STATUS_MASK is AND in) and is
sticky. The only way to reset it is for software
to write a zero into this bit. This bit goes to
the scaler to blank the scaler output.
A write to this reg will reset it to 0.
R
[6] 0x0
Indicates that one of the measured polarities
does not match the reference value.
R
[5] 0x0
Hsync (selected by SMEAS_H_SEL)
polarity.
0: active low
1: active high
R
[4] 0x0
Vsync (selected by SMEAS_V_SEL) polarity.
0: active low
1: active high
R
[3] 0x0
Indicates that the vertical pulse width
measurement exceeded the reference +/-
tolerance range.
R
[2] 0x0
Indicates that the horizontal per vertical
measurement exceeded the reference +/-
tolerance range.
R
[1] 0x0
Indicates that the XCLKs per horizontal
measurement exceeded the reference +/-
tolerance range.
R
[0] 0x0
Indicates that the XCLKs per vertical
measurement exceeded the reference +/-
tolerance range.

of each meas. No function on one-shot
mode.
