SC_RXOVFB
This bit is set when DMA receive buffer B was passed an overrun error from the lower hard-
ware FIFO. Neither receive buffers were 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. This bit is autocleared the
next time buffer B is loaded or when the receive DMA is reset.
This bit is set when DMA receive buffer A was passed an overrun error from the lower hard-
ware FIFO. Neither receive buffers were capable of accepting any more bytes (unloaded),
and the FIFO filled up. Buffer A 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. This bit is autocleared the
next time buffer A is loaded or when the receive DMA is reset.
This bit is set when DMA transmit buffer B is currently active.
This bit is set when DMA transmit buffer A is currently active.
This bit is set when DMA receive buffer B is currently active.
This bit is set when DMA receive buffer A is currently active.
A byte offset (from 0) which points to the location in DMA receive buffer A where the next
byte will be placed. When the buffer fills and subsequently unloads, this register wraps
around and holds the value zero (pointing back to the first location in the buffer).
