2 How to modify the value of PMMCOREVx in the boot code, and which file to modify?
3 In customer's application, the ADC reference voltage uses the external pin input power supply without using the internal reference voltage, which should have no effect on the AD sampling program. Which peripherals might these reference voltages be used for? Does it has an impact?
