Negative INT1 Polarity.
This bit selects whether the selected INT1 GPIO input will get inverted or pass as is
NEG_
before going to the edge detector. Note the edge detector detects either the rising
7
edge or both. The mode is selectable by EDGE_INT1 bit is separate register.
INT1
0: Pass the selected GPIO unchanged.
1: Inverts the selected GPIO.
INT1 Port Pin Selection Bits.
These bits select which Port pin is assigned to INT1.

Negative INT0 Polarity.
This bit selects whether the selected INT0 GPIO input will get inverted or pass as is
