PRELIMINARY
If ROCV_FREQ_SEL is set, the values programmed in
ROCV_FREQ_N[7:0] and ROCV_FREQ_M[6:0] will be
use to determine the recovery CPU output frequen-
cy.when a Watchdog timer time-out occurs.
The setting of FS_Override bit determines the frequency
ratio for CPU and other output clocks. When the
FS_Override bit is cleared, the same frequency ratio stat-
ed 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 the FS_Override bit determines the frequen-
cy 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.
