Evaluation data is available over communications via “portal” register reads. Each data 
item is assigned a portal register number. A block read of the specified size at that address 
will return the data for that item. In general, if the block size is smaller than specified, the 
data returned will be 0x8000 (-32768) to indicate the data is invalid. If the block size is 
larger than specified, the data for the item will be returned and the remaining registers will 
be padded with 0x8000. Refer to Table D–12 for portal register descriptions.
