IO channel to the system, open drain output. It is expected that an external pull-up resistor
will be provided to pull this signal up to V
in use this pin can be pulled to either V
Power supply, 2.5 – 5.5V. This pin should be bypassed with a high quality 0.1μF capacitor
close to this pin with a short trace to V
