Analog Reference
The CS_BOOT can be used to prevent the system to boot out of external memories (NandFlash, SPI
flash). The purpose is mainly to execute the SAM-BA part of the ROM code.
2 methods can be used:
The 3V voltage reference is based on a LM4040 (Precision Micropower Shunt Voltage Reference).
This ADVREF level can be set as 3V or 3.3V via the jumper JP14.
