5 FOS4_FLG FOS4_FLG.
CLKIN_4 Frequency Offset Flag.
0: Normal operation.
1: Held version of FOS4_INT. Generates active output interrupt if output interrupt pin is
enabled (INT_PIN=1) and if not masked by FOS4_MSK bit. Flag cleared by writing
location to 0.
4 FOS3_FLG FOS3_FLG.
CLKIN_3 Frequency Offset Flag.
0: Normal operation.
1: Held version of FOS3_INT. Generates active output interrupt if output interrupt pin is
enabled (INT_PIN=1) and if not masked by FOS3_MSK bit. Flag cleared by writing
location to 0.
3 FOS2_FLG 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 (INT_PIN = 1) and if not masked by FOS2_MSK bit. Flag cleared by writing
location to 0.
2 FOS1_FLG 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 (INT_PIN = 1) and if not masked by FOS1_MSK bit. Flag cleared by writing
location to 0.
1
LOL_FLG 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 (INT_PIN = 1) and if not masked by LOL_MSK bit. Flag cleared by writing
location to 0.
