Digital microphone 1 and 2 inputs (for bi-phase microphones), or digital microphone
1 input (for single-phase microphones).
Digital microphone 3 and 4 inputs (for bi-phase microphones), or digital microphone
2 input (for single-phase microphones).
Clock to drive external digital microphones.
General Purpose Input/Output Pins. Digital signals used to control or sense external
circuitry.
General Purpose I/O/Microphone Bias for Port E. Capable of Hi-Z, 1.65 V, and 2.86 V.
Pin 31 shares functionality between GPIO_1 (default) and MIC_BIAS_E. These
functions are mutually exclusive and the GPIO function takes priority over the
MIC_BIAS function. When the GPIO enable bit is 0, Pin 31 functions as a MIC_BIAS pin
associated with Port E.
EAPD/General Purpose Input/Output pin. Pin 47 shares functionality between
GPIO_0 and EAPD. These functions are mutually exclusive and the EAPD function
takes priority over the GPIO function. By default, the pin is in a Hi-Z state. External
resistors should be used to insure the proper circuit state when this pin is in Hi-Z.
S/PDIF_OUT – Supports S/PDIF output.
