START
n = 0, 1
Write more transmit data than the number set as the trigger by the UBnFIC2.UBnTT3 to
UBnFIC2.UBnTT0 bits to transmit FIFO.
This is the case where transmission is ended (transmit FIFO and the transmit shift register become
empty) before the next transmit data is written.
INTUBnTIF and INTUBnTIT signals and write the next data to transmit FIFO.
In the pending mode (UBnFIC0.UBnITM bit = 0), write as many transmit data as the number set as
the trigger by the UBnFIC2.UBnTT3 to UBnFIC2.UBnTT0 bits of to transmit FIFO. In the pointer
mode (UBnITM bit = 1), reference the UBnFIS1.UBnTB4 to UBnFIS1.UBnTB0 bits and write as
many data as the number of empty bytes in transmit FIFO to transmit FIFO.
Write 16-byte data to fully use the 8-bit × 16-stage FIFO function.
