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.

ROCV_FREQ_SEL
ROCV_FREQ_SEL determines the source of the recover
frequency when a Watchdog Timer time-out occurs. The
clock generator will automatically switch to the recovery
CPU frequency based on the selection on
ROCV_FREQ_SEL.
