7.2.2 Power-on Reset (POR) and Brown-out Detectors (BOD)
The PIC32CM SG00/GC00 embeds three features
to monitor, warn, and reset the device:
- A Power-on
Reset on VDD (AVDD and VDDIO):
- Monitoring is always activated, including during device startup or during any sleep modes
- Having VDD below a fixed threshold voltage will reset the whole device
Note: Refer to the Electrical Characteristics for the rising and falling threshold voltages. - A Brown-out
Detector (VDDBOD) on VDD (AVDD and VDDIO):
- The VDDBOD monitors VDD continuously
- dcBOR in (continuous mode) or periodically (sampled mode) with a programmable sample frequency in Backup mode
- A programmable threshold loaded from the NVM User Row is used to trigger an interrupt and/or reset the whole device
- PORCORE a
Brown-out Detector on VDDCORE Note: PORCORE is calibrated in production and its calibration parameters are stored in the NVM User Row. These data must not be changed to ensure correct device behavior.
