7.2.30 Interrupt Configuration Register B
Address 1Eh
Default 00h
7 6 5 4 3 2 1 0
Reserved Interrupt polarity B
Interrupt polarity B:
0 = Interrupt B is active low (default).
1 = Interrupt B is active high.
Interrupt polarity B must be same as interrupt polarity A bit at bit 0 of the 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.
