Description

RW DTX

Default TX value

Specifies what the RADIO will transmit when it is not

started, i.e. between:

RADIO.EVENTS_READY and RADIO.TASKS_START

RADIO.EVENTS_END and RADIO.TASKS_START

RADIO.EVENTS_END and RADIO.EVENTS_DISABLED

Note: For 802.15.4 and BLE LR mode, only

Center is a valid setting

Transmit '1'

Transmit '0'

Center

Transmit center frequency

When tuning the crystal for center frequency, the RADIO

must be set in DTX = Center mode to be able to achieve the

expected accuracy
