LOCKIF — PLL Lock Interrupt Flag
LOCK — Locked Phase Lock Loop Circuit
LHIF — Limp-Home Interrupt Flag
LHOME — Limp-Home Mode Status
To clear the flag, write one to this bit in PLLFLG. Cleared in limp-home
mode.
Regardless of the bandwidth control mode (automatic or manual):
Write has no effect on LOCK bit. This bit is cleared in limp-home mode as
the lock detector cannot operate without the reference frequency.
To clear the flag, write one to this bit in PLLFLG.
