I/O Function
O Serial data output of the external serial flash interface. Connects to
data input (DI) of external serial flash.
O Serial data CLK of the external serial flash interface.
I Serial data input to external serial flash interface. Connects to data
output (DO) of external flash memory.
O Chip Select Bar of the external serial flash interface.
O Digital power supply for the external flash memory. A minimum 1uF
capacitor with low ESR<0.5OHM should be connected to this pin for
supply decoupling and stability. Refer to the application diagram.
O Digital power supply for the external flash memory. A minimum 1uF
capacitor with low ESR<0.5OHM should be connected to this pin for
supply decoupling and stability. Refer to the application diagram.
I Digital power supply for the inbuilt voltage regulator for the external
flash memory. A 0.1uF capacitor should be connected to this pin for
supply decoupling and stability. Refer to the application diagram.
O Crystal interface output pin.
I The CLK_CFG register determines one of the following three
configurations: (1) A crystal or resonator connected between the
XTALOUT and XTALIN pins. (2) A resistor connected to GND as a
reference current to the internal oscillator and left the XTALOUT
unconnected. (3) An external clock input to the device and left the
XTALOUT unconnected.
This pin should be left unconnected.
This pin should be left unconnected.

This pin should be left unconnected.
O Aux Out. This pin is an analog voltage output.
If AUXOUT is not used, this pin should be left unconnected.
I Analog power supply pin.
I Analog ground pin.
O Middle voltage reference for the swing of analog/digital audio
outputs. A 4.7uF capacitor should be connected to this pin for
supply decoupling and stability.
This pin should be left unconnected.
