USB PLL Out-of-Range Status

This bit indicates whether the PLL is out of lock range.

Note: If PLL out-of-lock condition is detected then an interrupt is generated to the NVIC; software

can decide to relock the PLL or switch to PLL bypass mode in the interrupt handler.

USB PLL is not out of lock

USB PLL is out of lock

USB PLL Lock Status

This bit indicates whether the PLL is locked or not.

USB PLL is not locked

USB PLL is locked
