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 is not updated by subsequent errors until the buffer unloads and is reloaded, or the receive DMA is reset. 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 Reserved 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Reserved ADD[12:0] r r r r r rr rr rr r r Bits [31:13] Bits [12:0] The offset from the start of DMA receive buffer B of the first byte received with a parity, frame, or overflow error.
