This subsection provides a description of the clock module registers.
The Synthesizer Control Register (SYNCR) is read/write always.
LOLRE — Loss of Lock Reset Enable Bit
In external clock mode, the LOLRE bit has no effect.
The LOLRE bit 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.
