After 20 μs the analog voltage resulting from the converted data will start decreasing, therefore it
is necessary to refresh the channel on a regular basis to prevent this voltage loss. This is the
purpose of the REFRESH field in the DACC Mode Register where the user will define the period
for the analog channels to be refreshed.
Warning: A REFRESH PERIOD field set to 0 will disable the refresh function of the DACC
channels.
