iwdg: START and UNLOCK values before polling Busy
...
With code that uses IWDG and these operations:
- user code initializes iwdg
- user code jumps to USB-DFU
- USB host triggers a USB exit (e.g. after reflashing, or even just a
dummy dfu-util Reset/Exit command)
- user code will hang in iwdg_prescaler_busy() called from
iwdg_set_period_ms()
