I am encountering with a following problem in MCU STM32L432B.
1. When the MCU enter to low-power mode (Stop 2) ones does not wake up while VDD is low than 2.1V, instead of it turns to mode with power consumption more 10ma.
2.When operation of the MCU is normal I can decrease the VDD to the 1.7V (BOR level0) but after turn off power supply and then turn on power , the MCU does not run while VDD low than 2.1 V, ones too turns to mode with power consumption more 10ma.
