4 LOS4_FLG LOS4_FLG.
CKIN4 Loss-of-Signal Flag.
0: Normal operation.
1: Held version of LOS4_INT. Generates active output interrupt if output interrupt pin is
enabled (INT_PIN=1) and if not masked by LOS4_MSK bit. Flag cleared by writing
location to 0.
3 LOS3_FLG LOS3_FLG.
CKIN3 Loss-of-Signal Flag.
0: Normal operation.
1: Held version of LOS3_INT. Generates active output interrupt if output interrupt pin is
enabled (INT_PIN=1) and if not masked by LOS3_MSK bit. Flag cleared by writing
location to 0.
2 LOS2_FLG LOS2_FLG.
CKIN2 Loss-of-Signal Flag.
0: Normal operation.
1: Held version of LOS2_INT. Generates active output interrupt if output interrupt pin is
enabled (INT_PIN=1) and if not masked by LOS2_MSK bit. Flag cleared by writing
location to 0.
1 LOS1_FLG LOS1_FLG.
CKIN1 Loss-of-Signal Flag.
0: Normal operation.
1: Held version of LOS1_INT. Generates active output interrupt if output interrupt pin is
enabled (INT_PIN=1) and if not masked by LOS1_MSK bit. Flag cleared by writing
location to 0.
0 LOSX_FLG LOSX_FLG.
External reference (signal on pins XA/XB) Loss-of-Signal Flag.
0: Normal operation.
1: Held version of LOSX_INT. Generates active output interrupt if output interrupt pin is
enabled (INT_PIN=1) and if not masked by LOSX_MSK bit. Flag cleared by writing
location to 0.
