Result of the TDC conversion. The result is in clock edges of the
clock selected in [OSC_DIG.CTL0.ACLK_TDC_SRC_SEL]. Both
rising and falling edges are counted. When saturating the result is
slightly higher than the saturation limit, since it takes a non-zero time
to stop the measurement. The highest saturation limit is 24 bits (see
SATCFG.LIMIT) so maximum value of VALUE is hence slightly
above 2^24.
