Ground. Connect the exposed pad to GND1 and/or GND2.
Ground. Connect the exposed pad to GND1 and/or GND2.
Processor Interrupt (Active Low). Requires an external pull-up resistor. If this pin is not used, it
can be left floating.
Hardware Reset (Active Low). This pin resets the device to the default conditions. If not used,
this pin must be tied above V
