If ROCV_FREQ_SEL is set, the values programmed in
ROCV_FREQ_N[7:0] and ROCV_FREQ_M[6:0] will be
used to determine the recovery CPU output
frequency.when a Watchdog Timer time-out occurs.
The setting of FS_Override bit determines the frequency
ratio for CPU and other output clocks. When FS_Override
bit is cleared, the same frequency ratio stated in the
Latched FS[4:0] register will be used. When it is set, the
frequency ratio stated in the SEL[4:0] register will be used.

If Prog_Freq_EN is set, the values programmed in
CPU_FSEL_N[7:0] and CPU_FSEL_M[6:0] will be used
to determine the CPU output frequency. The new
frequency will start to load whenever CPU_FSELM[6:0] is
updated.
The setting of 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[4:0]
register will be used. When it is set, the frequency ratio
stated in the SEL[4:0] register will be used.
