A PLL reset is made if ...
Always
If GCM5 or GCM6 are written and their values N or M
change
If pinstrapping values change
Never
If pinstrapping values change
If actual values of N or M in GCM5 or GCM6 are
different to internal settings of the “clocking fixed mode”
If pinstrap values are different to internal settings of the
“clocking fixed mode”; That is not allowed!
