Tx FIFO Read Register
TFR | This field is only valid when FIFO access mode is enabled (UART_FAR[FAR] set to 1). When FIFOs are enabled, reading this field gives the data at the top of the Tx FIFO. Each consecutive read pops the Tx FIFO and gives the next data value that is currently at the top of the FIFO. When FIFOs are not enabled, reading it gives the data in the UART_THR[THR] field. |
