9.8.2.1 MTIM0 as ADC hardware trigger
MTIM0 overflow can be used as ADC hardware trigger. See ADC hardware trigger for
details.
9.8.3 Real-time counter (RTC)
The real-time counter (RTC) consists of one 16-bit counter, one 16-bit comparator,
several binary-based and decimal-based prescaler dividers, two clock sources, and one
programmable periodic interrupt. This module can be used for time-of-day, calendar or
any task scheduling functions. It can also serve as a cyclic wakeup from low power
modes without external components. RTC overflow trigger can be used as hardware
trigger for ADC module. Furthermore, when the trigger is enabled, RTC can toggle
external pin function if the counter overflows.
The following figure shows the device block diagram highlighting RTC module and pin.
