RX FIFO Interrupt (INT_RDA) Trigger Level
When the number of bytes in the receive FIFO equals the RFITL then the RDA_IF
will be set (if UA_IER [RDA_IEN] is enable, an interrupt will generated).
Reserved
TX Field Software Reset
When TX_RST is set, all the byte in the transmit FIFO and TX internal state machine
are cleared.
0 = Writing 0 to this bit has no effect.
1 = Writing 1 to this bit will reset the TX internal state machine and pointers.
Note: This bit will auto clear needs at least 3 UART engine clock cycles.
RX Field Software Reset
When RX_RST is set, all the byte in the receiver FIFO and RX internal state machine
are cleared.
0 = Writing 0 to this bit has no effect.
1 = Writing 1 to this bit will reset the RX internal state machine and pointers.
Note: This bit will auto clear needs at least 3 UART engine clock cycles.
