Ground.
Hardware Reset (Active Low). This bit resets the device to the power default conditions. The reset pin must be
driven for a minimum of 50 μs to be valid and to prevent falsing due to ESD glitches or noise in the system. If
not used, RST must be tied high with a pull-up.
V
I
I
Processor Interrupt, Active Low, Open Drain. This pin can be pulled up to 2.7 V or 1.8 V for selection flexibility in
the processor GPIO supply group.
Exposed Pad. The exposed pad must be connected to ground.
