5.2 Power-up Sequence

The voltage ramp-up on all V_DD pins must be closely matched during the power-up sequence to ensure proper operation.

The Power-On Reset (POR) and the Brown-out Detector (BOD) monitor V_DD and keep the system in Reset if the voltage level is below the respective thresholds. Refer to the RSTCTRL - Reset Controller and BOD - Brown-out Detector chapters for further information.

Refer to the Electrical Characteristics chapter for further information on voltage thresholds and supply voltage slope.
