LOS_MSK LOS_MSK.
Determines if a LOS on CKIN_q (LOS_FLG) is used in the generation of an interrupt.
Writes to this register do not change the value held in the LOS_FLG register.
0: LOS1 alarm triggers active interrupt on IRQ_q output (if INT_PIN=1).
1: LOS_FLG ignored in generating interrupt output.
0
LOSX_MSK LOSX_MSK.
Determines if a LOS on OSC 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 IRQ_q output (if INT_PIN=1).
1: LOSX_FLG ignored in generating interrupt output.
