1. Reduce the reference configuration to minimum requirements (0x, 1x, 3x, 4x).
Minimizing the state RAM area is one way to reduce scan time.
2. Another way is to define registers in a non-transfer area, an area contained within
the state RAM transfer area but ignored during the actual state RAM transfer.
3. Use the HSBY configuration extension to define transfer amounts.
Note: If you are customizing the size of your state RAM transfer area, you must
specify the number of each reference data type (0x, 1x, 3x, and 4x) as either 0 or
a multiple of 16. In the case of the 4x registers, there must always be at least 16
registers allotted.
