When the UART3.UART_LSR register is read, the UART3.UART_LSR[4:2] bit field reflects the error bits [FL, CRC, ABORT] of the frame at the top of the STATUS FIFO (the next frame status to be read).
The error is triggered by an interrupt (for IrDA mode interrupts, see Table 26-97). The STATUS FIFO must be read until empty (a maximum of eight reads is required).
