Enhanced Features (Variant 001 only)

Variant 001 of the DA16200 provides additional control over the priorities of the Wi-Fi TX, Wi-Fi RX

and BT/BLE and their usage of the RF antenna. This allows the DA16200 to control an RF antenna

switch directly through the BT_sig0 pin:

● BT_sig0 (oBtCoex_as)

○ Output - indicates WLAN is currently active

○ Can be used to directly control an RF switch

This allows DA16200 to be configured to control the RF antenna for many different scenarios. For

example, the Wi-Fi TX may have higher priority than BT/BLE, but Wi-Fi RX may have lower priority.
