CFME Bit (Clock Frequency Measurement Enable)
This bit specifies whether clock frequency measurement is enabled or disabled.
When rewriting this bit, more time is required than other bits for the new value to be reflected in the register. Further
write access to this bit are ignored until the current write access is reflected in the register. Read the bit to confirm that the
rewrite has been reflected in the register.
