Hmm, for brushless motor control there are 6 outputs from timer with 3 negated sones.

When the MCU is under reset, these GPIO are not driving the outputs, such as when reflashing the micro.

Maybe put weak pull-up/down on these lines to ensure safe operation.

Thank you

i will check and verify this point
