Alternatively two MIPI signals are also available to configure the external
antenna tuner.

The SW tool is available configure the table of antenna tuner parameters.
In-Device Coexistence Interface
As more and more radios are added to notebook and tablet the source of RF
interference increases significantly as multiple radios will have overlapping
transmissions and receptions. This problem will increase further as overlapping
bands continue to be rolled out. WLAN, BT, WWAN will all use overlapping
bands, ranging from 2300Mhz to 2600Mhz.
In-Device Coexistence is a feature which improves the user experience and
maximizes throughput and QoS of connectivity systems (WLAN, BT and
GNSS) when these radios are simultaneously running with the WWAN M.2
LTE modem.
These three COEX interfaces are provided to implement In-device wireless
coexistence solution.
