SIO Configuration
These registers configure and control the SIO channels. The registers include: the SIO local Arbiter Control register
that enables several priority options between the DMA channels that are assigned to the SIO; the Channel Flush/Reset
register that enables the CPU to clear the data from the DMA packing and unpacking registers; and the four Channel
Mode registers that define the device parameters (bus width, endianess), the shape of the control signals (pulse width,
burst support, turn-off width), and the DMA parameters (request polarity, arbitration boundaries, DMA direction, DMA
channel assignment). Note that channel 3 does not have DMA capabilities nor burst support. Channel 3 is for
CPU access only.
The Channel Flush/Reset register should only be written to the value of ‘1’. After completion of the Flush/Reset opera-
tion, the appropriate bit will be reset to ‘0’.

PrioOpt
Defines the arbiter behavior for the high priority device
0 - High priority device will relinquish the bus for a
requesting device for one DMA transaction.
1 - High priority device will be granted as long as it
requests the bus.

FlushRstCh0
During an SIO DMA read access, writing ‘1’ will flush
the contents of the packing register into the target
device on the AD bus. During an SIO DMA write
access, writing ‘1’ will clear the unpacking register.
