MAX-6 design
MAX-6 modules provide the following signals:
ANTON Signal (to turn on and off external LNA). To save power consumption in Power Save mode. See
section 2.6.9.
TX ready Signal (to trigger a host, e.g. a u-blox LEON wireless module, when data at DDC interface is ready
to be picked up). To save power consumption on Host side.
