Timer system features include:
13.1.3
This section defines the MTIM’s operation in stop, wait and background debug modes.
13.1.3.1
The MTIM continues to run in wait mode if enabled before executing the WAIT instruction. Therefore,
the MTIM can be used to bring the MCU out of wait mode if the timer overflow interrupt is enabled. For
lowest possible current consumption, the MTIM should be stopped by software if not needed as an
interrupt source during wait mode.
13.1.3.2
The MTIM is disabled in all stop modes, regardless of the settings before executing the STOP instruction.
Therefore, the MTIM cannot be used as a wake up source from stop modes.
Waking from stop1 and stop2 modes, the MTIM will be put into its reset state. If stop3 is exited with a
reset, the MTIM will be put into its reset state. If stop3 is exited with an interrupt, the MTIM continues
from the state it was in when stop3 was entered. If the counter was active upon entering stop3, the count
will resume from the current value.
13.1.3.3
The MTIM suspends all counting until the microcontroller returns to normal user operating mode.
Counting resumes from the suspended value as long as an MTIM reset did not occur (TRST written to a 1
