7.10 Power-Up Sequence

Characteristics of power-up sequence are as follows:

  • The VDD/AVDD domains must rise at the same time.
  • At Power-on Reset, the PIC32CX-BZ3 operates in the MLDO mode.
  • The LDOs start with their default settings and VDDCORE is powered-up.
  • The RF block is maintained in the Sleep mode during the power-up time.
  • The PMU controller switches the MLDO mode to DC-DC mode based on device settings in the Flash BCFG/TCFG area.
