THRE_IF
RDA_IF
Note: This bit is read only and reset to 0 when all bits of BIF, FEF and PEF are cleared.
Transmit Holding Register Empty Interrupt Flag (Read Only).
This bit is set when the last data of TX FIFO is transferred to Transmitter Shift Register.
If UA_IER [THRE_IEN] is enabled, the THRE interrupt will be generated.
Note: This bit is read only and it will be cleared when writing data into THR (TX FIFO
not empty).
Receive Data Available Interrupt Flag (Read Only).
When the number of bytes in the RX FIFO equals the RFITL then the RDA_IF will be
set. If UA_IER [RDA_IEN] is enabled, the RDA interrupt will be generated.
Note: This bit is read only and it will be cleared when the number of unread bytes of RX
FIFO drops below the threshold level (RFITL).
