1.11.1
Operating modes
AMY-6M modules only operate in Eco mode, this mode optimizes the use of the acquisition engine to deliver
lower current consumption.
Power Save Mode is not supported with AMY-6M.
1.11.2
Eco mode
In Eco mode, u-blox 6 receivers use the acquisition engine to search for new satellites only when needed for
navigation:
•
In cold starts, u-blox 6 searches for enough satellites to navigate and optimizes use of the acquisition
engine to download their ephemeris.
•
In non-cold starts, u-blox 6 focuses on searching for visible satellites whose orbits are known from the
Almanac.
In Eco mode, the u-blox 6 acquisition engine limits use of its searching resources to minimize power
consumption.
u-blox 6 deactivates the acquisition engine as soon as a position is fixed and a sufficient number (at least 4) of
satellites are being tracked. The tracking engine continues to search and track new satellites without orbit
information.
1.11.3
Base-band I/O supply voltage (VDD_IO)
The digital I/Os of the baseband part are supplied with VDD_IO from the host system. The wide range of VDD_IO
allows seamless interfacing to standard logic voltage levels independently of the baseband supply voltage level.
Without VDD_IO supply the system will be kept in reset state.
1.11.4
External DC/DC converter control
Pin DCDC_EN enables external DC/DC converter.
