1.4.16.2. Volume/Digital Microphone/GPIO Selection
There are 3 functions available on pins 2 and 4. To determine which function is actually enabled on
the 2 pins, the order of precedence is followed:
1. If the GPIOs are enabled, they override both Volume Control and Digital Mics
2. If the GPIOs are not enabled through the AFG, then at reset, the Volume control is enabled with

1.4.16.3. VRefOut/GPIO Selection
Two functions are available on pins 29, 31, and 37. To determine which function is actually enabled,
the order of precedence is followed:
1. If the GPIOx function is enabled, it overrides VRefOut-X
2. If the GPIO function is not enabled through the AFG, then the VrefOut function is enabled and in
