2 LOS2_MSK LOS2_MSK.
Determines if a LOS on CKIN2 (LOS2_FLG) is used in the generation of an interrupt.
Writes to this register do not change the value held in the LOS2_FLG register.
0: LOS2 alarm triggers active interrupt on INT_LOS1 output (if INT_PIN=1).
1: LOS2_FLG ignored in generating interrupt output.
1 LOS1_MSK LOS1_MSK.
Determines if a LOS on CKIN1 (LOS1_FLG) is used in the generation of an interrupt.
Writes to this register do not change the value held in the LOS1_FLG register.
0: LOS1 alarm triggers active interrupt on INT_LOS1 output (if INT_PIN=1).
1: LOS1_FLG ignored in generating interrupt output.
0 LOSX_MSK LOSX_MSK.
Determines if a LOS on XA/XB(LOSX_FLG) is used in the generation of an interrupt.
Writes to this register do not change the value held in the LOSX_FLG register.
0: LOSX alarm triggers active interrupt on INT_LOS1 output (if INT_PIN=1).
1: LOSX_FLG ignored in generating interrupt output.
