Recovery_Frequency
Vendor Test Mode (always program to 0)
This bit allows selection of the frequency setting that the clock will be
restored to once the system is rebooted
0: Use Hardware settings
1: Use Last SW table Programmed values
To enable this function the register bit must first be set to “0” before toggling
to “1”.
0: Do not reload
1: Reset timer but continue to count.
This bit is set to “1” when the Watchdog times out. It is reset to “0” when
the system clears the WD_TIMER time stamp
Watchdog timer time stamp selection:
0000: Off
0001: 2 second
0010: 4 seconds
0011: 6 seconds

If Prog_Freq_EN is set, the values programmed in CPU_FSEL_N[8:0] and
CPU_FSEL_M[6:0] will be used to determine the CPU output frequency.
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[E:A] register will be used. When it is set, the frequency
ratio stated in the SEL[4:0] register will be used.
