Rainbow Electronics MAX6871 - Manual (Page 24)

MAX6870/MAX6871
Table 14 only applies to PO4 of the MAX6870 and PO2
of the MAX6871. Write a 0 to a bit to make the PO4/PO2
output independent of the respective signal (IN_ primary
or secondary thresholds, WDI1 or WDI2, GPI1–GPI4, MR, or other programmable outputs). See Table 15 for
Product 2. PO4 (MAX6870)/PO2 (MAX6871) deasserts
when Product 1 or Product 2 = 1.
