Interrupt
polarity B
Interrupt polarity B
0 = Interrupt B is active low (default).
1 = Interrupt B is active high.
Interrupt polarity B must be the same as interrupt polarity A of Interrupt Configuration Register A at
Address C2h.
Interrupt Configuration Register B is used to configure the polarity of interrupt B on the external interrupt
pin. When the interrupt B is configured for active low, the pin is driven low when active and high
impedance when inactive (open-drain). Conversely, when the interrupt B is configured for active high, it is
driven high for active and driven low for inactive.
Note: An external pullup resistor (4.7 k
Ω to 10 kΩ) is required when the polarity of the external interrupt
terminal (pin 27) is configured as active low.
