Description
Interrupt Settings
(Reg 0x2C)
• INT Polarity Active Low
• INT Polarity Active High
• Active Low —the interrupt pins to sit at a logical high level (1), and to go
to logical low (0) when they are triggered.
• Active High —the interrupt pins to sit at a logical low level (0), and to go
to logical high (1) when they are triggered
.
• INT Push/Pull
• INT Open Drain
• Push/Pull — Activates two transistors on the interrupt pins that push up
or pull down the output to the desired level.
This is the default setting.
• Open Drain— When selected, the interrupt pins will be open drain,
which allows multiple interrupt signals to be connected to the same
interrupt line.
