Source address modulo feature is disabled
This value defines a specific address range specified to be the value after SADDR + SOFF
calculation is performed or the original register value. The setting of this field provides the ability to
implement a circular data queue easily. For data queues requiring power-of-2 size bytes, the queue
should start at a 0-modulo-size address and the SMOD field should be set to the appropriate value
for the queue, freezing the desired number of upper address bits. The value programmed into this
field specifies the number of lower address bits allowed to change. For a circular queue application,
the SOFF is typically set to the transfer size to implement post-increment addressing with the SMOD
function constraining the addresses to a 0-modulo-size range.
