I found there is no [LOCF] bit in PLLDIG_PLL0SR Register,but it has been mentioned in the description of PLL0CR[LOCIE].
Where is the [LOCF]?
MPC5744PRM_Rev5.pdf Page 777
LOLF is Loss-of-lock flag,and it is corresponding to LOLIE(Loss-of-lock interrupt enable)
According to LOCIE(Loss-of-clock interrupt request),I think LOCF means Loss-of-clock.
So LOCF must be missed in PLLDIG_PLL0SR.
