31-25 RESERVED R X

Software should not rely on the value of a reserved. Writing any

other value than the reset value may result in undefined behavior.

24-0 VALUE R 2h

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.
