If a read of the LOCS flag and a loss of clock condition occur
simultaneously, the flag does not reflect the current loss of clock
condition.
A loss of clock condition can be detected only if LOCEN = 1 or the
oscillator has not yet returned from exit from stop mode with
FWKUP = 1.
NOTE:
The LOCS flag is always 0 in external clock mode.
