(5) Reception timeout interrupt request signal (INTUBTITO)
(a) Single mode
(b) FIFO mode
Cannot be used.
The reception timeout interrupt request signal is generated if data is stored in receive FIFO when the next
data does not come (start bit is not detected) even after the next data reception wait time specified by the
UBFIC1.UBTC4 to UBFIC1.UBTC0 bits has elapsed, when the timeout counter function is used
(UBFIC1.UBTCE bit = 1).
The reception timeout interrupt request signal is not generated while reception is disabled.
If receive data of the number set as the trigger by the UBFIC2.UBRT3 to UBFIC2.UBRT0 bits is not
received, the timing of reading the number of receive data less than the specified number can be set by
the reception timeout interrupt request signal.
Since the timeout counter starts counting at start bit detection, a receive timeout interrupt request signal
does not occur if data of 1 character has not been received.
