FOS2_FLG CLKIN_2 Frequency Offset Flag.
0: Normal operation.
1: Held version of FOS2_INT. Generates active output interrupt if output interrupt pin is
enabled (IRQ_PIN = 1) and if not masked by FOS2_MSK bit. Flag cleared by writing 0 to
this bit.
2
FOS1_FLG CLKIN_1 Frequency Offset Flag.
0: Normal operation
1: Held version of FOS1_INT. Generates active output interrupt if output interrupt pin is
enabled (IRQ_PIN = 1) and if not masked by FOS1_MSK bit. Flag cleared by writing 0 to
this bit.
1
LOL_FLG PLL Loss of Lock Flag.
0: PLL locked
1: Held version of LOL_INT. Generates active output interrupt if output interrupt pin is
enabled (IRQ_PIN = 1) and if not masked by LOL_MSK bit. Flag cleared by writing 0 to
this bit.
