7.4 Power-on Reset and Brown-out Reset

The PIC32CK SG/GC family of devices embed the following features to monitor, warn, and reset the device:

  • POR: Power-on Reset on the main supply VDD (AVDD)
  • dcBOR: Duty cycled Brown-out Reset on VDDREG/AVDD/VDDIO
  • VDDBORxx: Brown-out Reset on VDDREG/AVDD/VDDIO/VDDUSB3V
  • PORCORE: Brown-out Detector internal to the VDDCORE_SW power domain. The PORCORE is calibrated in production and its calibration parameters are stored in the USER CFG page. This data should not be changed if the User Row is written to assure correct behavior.
    Note: The output of the USB PHY regulators is monitored by the SUPC.
