How to stop and then re-start one-shot timer?

spi5 will not do less then 8 multiplier.

I set up my spi5 as follows hspi5.Init.Mode = SPI_MODE_MASTER; hspi5.Init.Direction = SPI_DIRECTION_2LINES; hspi5.Init.DataSize = SPI_DATASIZE_8BIT; hspi5.Init.CLKPolarity = SPI_POLARITY_LOW; hspi5.Init.CLKPhase = SPI_PHASE_2EDGE; hspi5.Ini...

I am using STM32L443 processor. When the processor is locked, I reset the processor with NRST with external wdg. The processor is not reset although WDG is working properly.

I checked WDG. The system is working properly. If there is no reset, it resets when I disable the WDG signal. In case of deadlock, I pull to GND myself, but it still does not reset. The only solution is to cut off all energy.

When I program my device in debugging via JTAG/SWD with instances of low-power STOP mode within the code and disconnect Debugger, device never goes to sleep and get Ghost wake-up INTs. However, if I power cycle not pin reset device, every thing works.

Is there registers set by JTAG/SWD preventing sleep after programming.I also experience the same behavior after programming and reset within the STM32 ST-LINK Utility and not only within the IDE
