Radio front end control signals
In general, three different radio control signal can be extracted from DA14580:
-
extrc_txen, it can be used as Tx_En control signal of the RF front end.
-
extrc_rxen or radcntl_rxen radio. Both signals are of the same duration. They can be used
as Rx_En control signals for the RF front end.
-
event_in_process that can be used for wlan co-existence signal.
The signals are extracted by using the BLE diagnostic port. Two registers need to be programmed:
-
BLE_DIAGCNTL_REG where it is defined which signals will be extracted from each port.
