Alarms and Warnings Interrupt Source Masking
Alarm and warning violations set the flags in the Alarm
and Warning Status Registers, and also assert the
interrupt output if they are not masked. If an alarm or
warning is masked, it will not set the interrupt. Table 8
shows the locations of the masking bits. The warning or
alarm is masked if the corresponding bit is set to 1.
