13.9 Start-up Considerations
The presence of hardware NVR fuses on the PIC32CX-BZ2 device allows the system configuration fuses to be ready upon exiting Reset. The following start-up conditions exist:
- On any device Reset, no start-up time is required to transfer configuration values from the NVR memory into the configuration holding registers.
- Once the device is active, the user may change the primary system clock source from FRC to SPLL by using the OSCCON register.
