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.
Indicates that one of the measured polarities
does not match the reference value.

polarity.
0: active low

Indicates that the vertical pulse width
measurement exceeded the reference ±
tolerance range.
Indicates that the horizontal per vertical
measurement exceeded the reference ±
tolerance range.
Indicates that the XCLKs per horizontal
measurement exceeded the reference ±
tolerance range.
Indicates that the XCLKs per vertical
measurement exceeded the reference ±
tolerance range.
