TXDB (output)
In the FIFO mode, the INTUBTIT signal occurs at the above timing when as many transmit data as
the number set as the trigger by the UBFIC2.UBTT3 to UBFIC2.UBTT0 bits are serially transferred.
The INTUBTIF signal occurs at the above timing when data is no longer in transmit FIFO and the
transmit shift register (when the FIFO and register are empty).
