Bits [12:0] SC_RXERRB: The offset from the start of DMA receive buffer B of the first byte received with a
parity, frame, or overflow error. Note that an overflow error occurs at the input to the receive
FIFO, so this offset is 4 bytes before the overflow position. If there is no error, it reads zero. This
register will not be updated by subsequent errors until the buffer unloads and is reloaded, or the
receive DMA is reset.
