CME — Clock Monitor Enable
The VDDPLL-dependent reset operation is not implemented on first
pass products.
In this case the state of CME on reset is 0.
FCME — Force Clock Monitor Enable
Read and write anytime.
If FCME is set, this bit has no meaning nor effect.
On reset
Write once in normal modes, anytime in special modes. Read
anytime.
In normal modes, when this bit is set, the clock monitor function
cannot be disabled until a reset occurs.
