Power Control
The R4 Series GPS Receiver module offers two power control modes: Full
Power and Hibernate. In Full Power mode the module is fully active and
and continuously tracking. Measurements are of the highest quality and are
continuously output by the module. This is the highest current consumption
state.
Hibernate mode is the lowest power setting. The tracking and processor
blocks are powered down, but the RTC is still running and the memory
blocks are still powered enabling a hot start.
The module switches between these states by toggling the ON_OFF line.
The ON_OFF line must go high for at least 100ms to trigger the change of
state and must remain low for at least 100ms to reset the edge detector.
If the module is in Full Power mode, a pulse on the ON_OFF line will initiate
an orderly shutdown into Hibernate mode. If the module is in Hibernate
mode, a pulse on the ON_OFF line will transistion the module into Full
Power Mode.
