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.
