CPU_DAF_N7
If Prog_CPU_EN is set, the values programmed in CPU_DAF_N[8:0] and
CPU_DAF_M[6:0] will be used to determine the CPU output frequency.
The setting of the FS_Override bit determines the frequency ratio for CPU
and other output clocks. When it is cleared, the same frequency ratio
stated in the Latched FS[E:A] register will be used. When it is set, the
frequency ratio stated in the FSEL[3:0] register will be used.
