ning of each series of consecutive reads. Software must check if the smaRTClock Interface is busy prior to
reading RTC0DAT. Autoread is enabled by setting AUTORD (RTC0ADR.6) to logic 1.
20.1.4. RTC0ADR Autoincrement Feature
For ease of reading and writing the 48-bit CAPTURE and ALARM values, RTC0ADR automatically incre-
ments after each read or write to a CAPTUREn or ALARMn register. This speeds up the process of setting
an alarm or reading the current smaRTClock timer value.
