See CPU Frequency Select Table
Default value corresponds to 200MHz.
Note that Selected HTT frequency tracks the
CPU frequency.
See SRC Frequency Select Table
Note: SB_SRC and ATIG Clocks are
synchronous to these outputs. Changing this
frequency will alter the SB_SRC and ATIG
frequency by the same percentage.
