P_Down/RST Power Down; When high, places the module in the low

power stand-by mode and on the falling edge of P_Down

initiates a module reset

Reset; The falling edge initiates a complete reset of the

module including the 2-wire serial interface, equivalent to a

power cycle.

Notes:

1. Module circuit ground is isolated from module chassis ground within the module.

2. Open collector; should be pulled up with 4.7k – 10kohms on host board to a voltage between 3.15V

and 3.6V.
