when = 1, TX0 FIFO has underflowed.
when = 1, RX0 FIFO has overflowed and the FIFO pointer
is currently pointing at the last data received before the
overflow occurred.
when = 1, RX1 FIFO has overflowed and the FIFO pointer
is currently pointing at the last data received before the
overflow occurred.
when = 1, RX2 FIFO has overflowed and the FIFO pointer
is currently pointing at the last data received before the
overflow occurred.
when = 1, the tx0 FIFO is full and an attempt has been
made to write data to it by the APB or DMA. This bit is
cleared by writing a 0 to it.
