I2C Master Port
The I2C master port is used to communicate with external audio devices such as
a sub-woofer amplifier. It is assumed that external pull up resistors are included
on the application board.
GPIOs
3.3V CMOS logic level GPIOs available to connect to other devices, or to use as
UI supporting GPIOs for LED and button support. All supported GPIOs can be
configured as outputs or inputs with configurable pull-ups/pull-downs.
