WR_DMA_TERM
DMA Buffer Termination
After a DMA Buffer was terminated, depending on which
bits are set in this array, the reason(s) for the termination
are indicated.
These bits are automatically cleared when a new DMA
Buffer is provided by writing to the DMA Buffer Length
Register.
Bit 22: Error
The Input Unit operation is stopped before the desired
Number of Conversions has been performed because a
Conversion Error or a FIFO Overflow occurred.
Bit 21: Block/Frame End
The desired number of samples (configured in the
Number of Conversions Register) has been written to
DMA Buffers.
Bit 20: Buffer End
The end of the DMA Buffer was reached (the DMA Buffer
is full). A new DMA Buffer must be provided.
