24.3.3.12 Task Size Registers (TSKSZ[0:1])
Each of the 16 tasks can be programmed to use specific source and destination sizes contained in a task
size register instead of a specific type encoded in a DRD. The ADS module uses the task size register
information to determine the source and destination transfer size of the operands. When the size contained
in the DRD is set to 2’b11 then specific source and destination size fields from the task size register are
selected.
