MAX6872/MAX6873
EEPROM-Programmable, Hex/Quad,
Power-Supply Sequencers/Supervisors
______________________________________________________________________________________

Table 15 only applies to PO5 of the MAX6872 and PO3
of the MAX6873. Write a 0 to a bit to make the PO5/PO3
output independent of the respective signal (IN_ primary
or secondary thresholds, WD1 or WD2, GPI1–GPI4, MR,
or other programmable outputs). See Table 14 for
Product 1. PO5 (MAX6872)/PO3 (MAX6873) deasserts
when Product 1 or Product 2 = 1.
