Hello, may I ask if the CHF bit will still be set to 1 when the FTM module triggers an interrupt event in VLPS mode .

The FTM is not a wakeup source.

RM, Table 7-8. AWIC stop and VLPS wake-up sources

The module is not functional in VLPS.

RM, Table 39-4. Module operation in available power modes

Hello, during testing, it was found that the FTM module can still be set to CHF after about 20ms of sleep for the first time. Is this a chip feature?

FTM is not supported in VLPS and should be disabled before the MCU enters VLPS, we can't guarantee FTM functionality in VLPS.
