In the SYNSR, only the LOLF and LOCF flag bits are writeable. Writes to bits other than LOLF
and LOCF have no effect.

Loss-of-lock flag. This bit provides the interrupt request flag. To clear the flag, write a 1 to
this bit. Writing 0 has no effect.
This flag will not be set and an interrupt will not be requested under any one of the following
conditions: (1) loss-of-lock caused by system reset, (2) writing to the SYNCR to modify the
MFD bits, or (3) enabling frequency modulation. The only way to clear this flag is to reset
the part or write a 1 to this bit.
0 Interrupt service not requested
1 Interrupt service requested
Loss-of-clock status. This bit is an indication of whether a loss-of-clock condition is present
when operating in normal and 1:1 PLL modes. If LOC = 0, the system clocks are operating
normally. If LOC = 1, the system clocks have failed due to a reference failure or a PLL
failure. If the read of the LOC bit and the loss-of-clock condition occur simultaneously, the
bit does not reflect the current loss-of-clock condition. If a loss-of-clock condition occurs
which sets this bit and the clocks later return to normal, this bit will be cleared.
A loss-of-clock condition can only be detected if LOCEN = 1. See
Operation During Reset.”
Note: LOC is always cleared in external clock mode.
0 Clocks are operating normally
1 Clocks are not operating normally.
