The MFX IRQ_OUT pin is unique and common to all functionalities, so if several
functionalities are configured in exit mode, the MCU has to enquire MFX about
the IRQ source (see BSP_IO_ITGetStatus). Communication with Mfx is done by I2C.
Often the sw requires ISRs (irq service routines) to be quick while communication
with I2C can be considered relatively long (hundreds of usec depending on I2C clk).
Considering that the features for human interaction like TS, Joystick, SD detection
don�t need immediate reaction, it is suggested to use POLLING instead of EXTI mode,
in order to avoid "blocking I2C communication" on interrupt service routines */

On ISR a flag is set (MfxIrqReceived), the main loop polls on the flag;
Mcu communicates with Mfx only when the flag has been set. This is just an example:
the users should choose they strategy depending on their application needs.*/
