Bits [12:0] SC_TXBEGA: DMA transmit buffer A start address.
Transmit DMA begin address register A (SCx_TXBEGA)
Address offset: 0xC810 (SC1_TXBEGA) and 0xC010 (SC2_TXBEGA)
Reset value:
Transmit DMA begin address register B (SCx_TXBEGB)
Address offset: 0xC818 (SC1_TXBEGB) and 0xC018 (SC2_TXBEGB)
Reset value:
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.
Bit 2 This bit is set when DMA transmit buffer A is active.
Bit 1 This bit is set when DMA receive buffer B is active.
Bit 0 This bit is set when DMA receive buffer A is active.

It is cleared the next time buffer A is loaded or when the receive DMA is reset. (SC1 in UART
mode only)
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.
