Bit 9 SC_RXFRMB: This bit is set when DMA receive buffer B reads a byte with a frame error from
Bit 8 SC_RXFRMA: This bit is set when DMA receive buffer A reads a byte with a frame error from
Bit 7 This bit is set when DMA receive buffer B reads a byte with a parity error from the receive FIFO.
Bit 6 This bit is set when DMA receive buffer A reads a byte with a parity error from the receive FIFO.
Bit 5 This bit is set when DMA receive buffer B was passed an overrun error from the receive FIFO.
Bit 4 This bit is set when DMA receive buffer A was passed an overrun error from the receive FIFO.
Bit 3 This bit is set when DMA transmit buffer B is active.

Neither receive buffer was capable of accepting any more bytes (unloaded), and the FIFO filled
up. Buffer B was the next buffer to load, and when it drained the FIFO the overrun error was
passed up to the DMA and flagged with this bit. Cleared the next time buffer B is loaded and
when the receive DMA is reset.

0: No count was saved because nSSEL did not deassert.
2: Buffer A's count was saved, nSSEL deasserted once.
3: Buffer B's count was saved, nSSEL deasserted once.
6: Buffer A's count was saved, nSSEL deasserted more than once.
7: Buffer B's count was saved, nSSEL deasserted more than once.
