//! \brief Set the configuration of an IO port.
//!
//! This function is used to configure the functionality of an IO.
//!
//! The \c ui32IOId parameter specifies which IO to configure.
//!
//! The \c ui32PortId parameter specifies which functional peripheral to hook
//! up to this IO.
//!
//! The \c ui32IOConfig parameter consists of a bitwise OR'ed value of all
//! the available configuration modes
//!
//! \note All IO Ports are tied to a specific functionality in a sub module
//! except for the \ref IOC_PORT_AUX_IO. Each of the IOs in the AUX domain are
//! hardcoded to a specific IO. When enabling one or more pins for the AUX
//! domain, they should all be configured to using \ref IOC_PORT_AUX_IO.
//!
//! \param ui32IOId defines the IO to configure and must be one of the following:
//! - \ref IOID_0
//! - ...
//! - \ref IOID_31
//! \param ui32PortId selects the functional IO port to connect.
//! The available IO ports are:
//! - \ref IOC_PORT_GPIO

//! - \ref IOC_PORT_AUX_IO
//! - \ref IOC_PORT_MCU_SSI0_RX
