The wake-up interrupt for IrDA mode has the same function as that for UART mode (see Section 26.3.4.5.1.2, Wake-Up Interrupt).
Wake-up interface implementation in this mode is based on the UARTi_SIDLEACK low-to-high transition instead of the UARTi_SIDLEACK state.
This does not ensure wake-up event generation as expected when configured in smart-idle mode, and the system wakes up for a short period.
