UNLOCK_ONCE This bit is a sticking indication of FMPLL loss of lock condition. UNLOCK_ONCE is set when the
FMPLL loses lock. Whenever the FMPLL reacquires lock, UNLOCK_ONCE remains set. Only a
power-on reset clears this bit.
I_LOCK This bit is set by hardware whenever there is a lock/unlock event.
S_LOCK This bit is an indication of whether the FMPLL has acquired lock.
0: FMPLL unlocked
1: FMPLL locked
Note:
PLL_FAIL_MASK This bit is used to mask the pll_fail output.
0 pll_fail not masked.
1 pll_fail masked.
PLL_FAIL_FLAG This bit is asynchronously set by hardware whenever a loss of lock event occurs while FMPLL
is switched on. It is cleared by software writing ‘1’.
