MON3almhi: High Alarm Status for MON3 measurement.
0 = MON3 measurement is below set limit.
1 = MON3 measurement is above set limit.
MON3almlo: Low Alarm Status for MON3 measurement.
0 = MON3 measurement is above set limit.
1 = MON3 measurement is below set limit.

MINT: Maskable Interrupt. An interrupt output signal that is determined by unmasked alarm and
warning flags. Masks of alarm and warning flags are located in Table 01h (Table 00h in DS1859
configuration), bytes F8h through FBh, or Table 05h, bytes F8h through FBh, depending on the state
of the MASK bit (Table 04h (Table 01h in DS1859 configuration), byte DAh, bit 0), and determine the
state of MINT. MINT is maskable to 0 if no interrupt is desired by setting bytes F8h through FBh to a
value of 00h.
MON3lo
Determined after each channel’s first analog-to-digital conversion.
