37.1.3 Modes of Operation
When the MCU is in active BDM background or BDM foreground mode, the FTM
temporarily suspends all counting until the MCU returns to normal user operating mode.
During stop mode, all FTM input clocks are stopped, so the FTM is effectively disabled
until clocks resume. During wait mode, the FTM continues to operate normally. If the
FTM does not need to produce a real time reference or provide the interrupt sources
needed to wake the MCU from wait mode, the power can then be saved by disabling
FTM functions before entering wait mode.
