Description
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
This flag gets set if DMA buffer 1 has been emptied by the SPDO
hardware. The flag can be cleared only by a software write to
ACK_BUF1.
This flag gets set if DMA buffer 2 has been emptied by the SPDO
hardware. The flag can be cleared only by a software write to
ACK_BUF2.
Bandwidth Error. This flag gets set if the internal buffers in SPDO
were emptied before new memory data was brought in. This flag
can be cleared only by a software write to ACK_HBE.
This flag gets set if both DMA buffers were emptied before a new full
buffer was assigned by software. The hardware has performed a
normal buffer switch over and is emitting old data. It can only be
cleared by software write to ACK_UDR.
This flag gets set if the hardware is currently emitting DMA buffer 1
data, and is negated when emitting DMA buffer 2 data.
1 =Software Reset. Immediately resets the SPDO block. This
should be used with extreme caution. Any ongoing transmission will
be interrupted, and receivers may be left in a strange state.
1 =Enables transmission as per the selected mode.
0 =Transmission Disabled. Stops any ongoing transmission after
completing any actions related to the current data descriptor word.
