picoPower-Slide6

Since there is no need for the BOD while the MCU is in the deep sleep mode, the picoPower BOD can be turned off in Extended Standby, Standby, Power Save, and Power Down modes. The picoPower BOD-disable feature is enabled by the application using a two-step secure operation and is fully automatic. When entering sleep, the BOD is disabled after the MCU has entered the sleep mode. It is enabled to verify that the power supply is sufficient before the MCU is allowed to wake from sleep. If the power supply is not sufficient, the MCU will enter a reset mode before any code execution takes place.
