FUNCTION DESCRIPTION
0: Output frequency depend on frequency table
1: Program all clock frequency by changing M/N
value
The equation is
0
VCO =14.318MHz*(N+4)/ M.
Once the watchdog timer timeout, the bit will be
clear. Then the frequency will be decided by
hardware default FS<4:0> or desired frequency
select SAF_FREQ[4:0] depend on
EN_SAFE_FREQ (Reg0 – bit0).
