Loss of lock reset enable. Determines how the system handles a loss of lock
indication. When operating in normal mode or 1:1 PLL mode, the PLL must be locked
before setting the LOLRE bit. Otherwise reset is immediately asserted. To prevent an
immediate reset, the LOLRE bit must be cleared before writing the MFD[2:0] bits or
entering stop mode with the PLL disabled.
1 Reset on loss of lock
0 No reset on loss of lock
Note: In external clock mode, the LOLRE bit has no effect.
