Rainbow Electronics MAX6871 User Manual
Page 27
Table 17 only applies to PO5 of the MAX6870 and PO3
of the MAX6871. Write a 0 to a bit to make the PO5/PO3
output independent of the respective signal (IN_ primary
or secondary thresholds, WDI1 or WDI2, GPI1–GPI4,
MR, or other programmable outputs). See Table 16 for
Product 1. PO5 (MAX6870)/PO3 (MAX6871) deasserts
when Product 1 or Product 2 = 1.
