MAX6870/MAX6871
Table 18 only applies to PO6 of the MAX6870 and PO4
of the MAX6871. Write a 0 to a bit to make the PO6/PO4
output independent of the respective signal (IN_ primary
or secondary thresholds, WDI1 or WDI2, GPI1–GPI4,
MR, or other programmable outputs). See Table 19 for
Product 2. PO6 (MAX6870)/PO4 (MAX6871) deasserts
when Product 1 or Product 2 = 1.
