Evaluation Data Available Over a Communications Link
Portal Registers
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 C–5 for portal register descriptions.
