Description
Valid data. Used to notify when the data is valid (a new value has been written). It is
automatically cleared when data is read.
Overwrite data. Used to notify when a conversion data is overwritten by a newer result. The
new data is written or discarded according to the MCR[OWREN] bit value.
Test channel converted data
