Power-on resets (POR HV and POR LV)
The STM32W108C8 measures the voltage levels supplied to the three power domains. If a
supply voltage drops below a low threshold, then a reset is applied. The reset is released if
the supply voltage rises above a high threshold. There are three detection circuits for power
on reset as follows:
