Reserved. In normal functional mode, these bits MUST be set to zero.
Output Jitter Performance Bits: These bits are used to control the DPLL output jitter
performance with respect to the noise received through the output pins. The higher
value (unsigned) means more filtering, while zero means filter bypass. The default
