RFL

         Receive FIFO Level.
This register is valid only when the DW_apb_uart is configured to have additional FIFO status registers
implemented (FIFO_STAT = YES). If status registers are not implemented, this register does not exist and
reading from this register address returns 0.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
