21 LVTTL-I P_Down/RST Power down; When high, requires the module to limit power
consumption to 1.5W or below. 2-Wire serial interface must
be functional in the low power mode.
Reset; The falling edge initiates a complete reset of the
module including the2-wire serial interface, equivalent to a
power cycle.

Notes:
1. Module ground pins GND are isolated from the module case and chassis ground within the module.
2. Shall be pulled up with 4.7K-10Kohms to a voltage between 3.15V and 3.45V on the host board.
3. The pins are open within module.
4. Reference Clock is not required
