Table 6. Config Register Field Descriptions (continued)
Bit Field Type Reset Description
4 COMP_MODE R/W 0h
Comparator mode (ADS1014 and ADS1015 only)
This bit configures the comparator operating mode. This bit serves no function on
the ADS1013.
0 : Traditional comparator (default)
1 : Window comparator
3 COMP_POL R/W 0h
Comparator polarity (ADS1014 and ADS1015 only)
This bit controls the polarity of the ALERT/RDY pin. This bit serves no function on
the ADS1013.
0 : Active low (default)
1 : Active high
2 COMP_LAT R/W 0h
Latching comparator (ADS1014 and ADS1015 only)
This bit controls whether the ALERT/RDY pin latches after being asserted or
clears after conversions are within the margin of the upper and lower threshold
values. This bit serves no function on the ADS1013.
0 : Nonlatching comparator . The ALERT/RDY pin does not latch when asserted
(default).
1 : Latching comparator. The asserted ALERT/RDY pin remains latched until
conversion data are read by the master or an appropriate SMBus alert response
is sent by the master. The device responds with its address, and it is the lowest
address currently asserting the ALERT/RDY bus line.
1:0 COMP_QUE[1:0] R/W 3h
Comparator queue and disable (ADS1014 and ADS1015 only)
These bits perform two functions. When set to 11, the comparator is disabled and
the ALERT/RDY pin is set to a high-impedance state. When set to any other
value, the ALERT/RDY pin and the comparator function are enabled, and the set
value determines the number of successive conversions exceeding the upper or
lower threshold required before asserting the ALERT/RDY pin. These bits serve
no function on the ADS1013.
00 : Assert after one conversion
01 : Assert after two conversions
10 : Assert after four conversions
11 : Disable comparator and set ALERT/RDY pin to high-impedance (default)
