needed.

Not connected in current DevelBoard Blue version. Currently ADCVREF of the CPU is connected to the

3.3V power supply. For normal operation leave this pin unconnected.

For normal operation, this pin can be driven low or left unconnected. If driven high, this pin disables the CE

something goes wrong during development or if you want the CPU to boot from other devices.
