Operating conditions at power-up
Power-on resets (POR HV and POR LV)
The STM32W108 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:

Table 39.
Table 40.
The POR LVcore and POR LVmem reset sources are merged to provide a single reset
source, POR LV, to the Reset Generation module, since the detection of either event needs
to reset the same system modules.
