In all IR modes, when address checking is enabled by setting the UART3.UART_EFR[1:0] bit field (see Table 24-87), only frames intended for the device are written to the RX FIFO. This is to avoid receiving frames not meant for this device in a multipoint infrared environment. To program two frame addresses that the UART3 receives in IrDA mode, use the UART3.UART_XON1_ADDR1[7:0] and UART3.UART_XON2_ADDR2[7:0] bit fields.
