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 (IRQ_PIN = 1) and if not masked by LOS2_MSK bit. Flag cleared by writing 0 to
this bit.
1
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 (IRQ_PIN = 1) and if not masked by LOS1_MSK bit. Flag cleared by writing 0 to
this bit.
0
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 (IRQ_PIN = 1) and if not masked by LOSX_MSK bit. Flag cleared by writing 0 to
this bit.
