//! This section covers the definitions that control which hardware is used to
//! communicate with the TRF79x0 EM module.  These defines configure which SSI
//! peripheral is used as well as which pins are assigned to the other
//! connections to the TRF79x0 EM module.  The \b TRF79X0_SSI_* defines are
//! used to specify the SSI peripheral that is used by the application.  The
//! remaining defines specify the pins used by the NFC APIs.  The TRF79x0
//! EM module requires the following signal connections: CLK, RX, TX, CS, ASKOK,
//! EN, EN2, IRQ, MOD.  To configure these signals, three defines must be set
//! for each. For example, for the CS signal, the \ref TRF79X0_CS_BASE,
//! \ref TRF79X0_CS_PERIPH and \ref TRF79X0_CS_PIN defines must be set.
//!
//! \b Example:  CS pin is on GPIO port E pin 1.
