(11) Example of reception error processing flow in FIFO mode (2)
Caution Reception can be continued by completing this control flow before reception of the next
data is ended. Extract the receive data and check if a reception error has occurred before
receive FIFO becomes empty. Note that this control flow is valid only when a parity error or
a framing error occurs.
(UBFIC0.UBRFC bit = 1).
If the next data is received before this control flow is ended, a reception error interrupt
request signal (INTUBTIRE) may occur even if the data has been received correctly.
