PLL Loss of Lock (LOL).
Asserts when the two PFD inputs have a frequency difference > 1000 ppm.
This bit is held high during a POR_reset until the PLL has locked. This bit will not
chatter while the PLL is locking. PLL_LOL does not assert when the input from
IN1,IN2 or IN3 is lost. When PLL_LOL asserts, the part will automatically try to
re-acquire to the input clock. See Register 241[7].
Loss of Signal on Feedback Clock from IN5,6 or IN4.
