PRODUCTION DATA.
The value in the Consecutive Alert Register (address 22h) determines how many consecutive out-of-limit measurements must occur on a measurement channel before the ALERT or the THERM signal is activated. The value in this register does not affect bits in the Status Register. Values of one, two, three, or four consecutive conversions can be selected; one conversion is the default. This function allows additional filtering for the ALERT or the THERM pin. Table 14 shows the consecutive alert bits. For bit descriptions, see Table 12.
