The most basic way to transmit a data frame is through software. Each step must be handled by the application. To send a data frame using software, the following steps must be executed. Steps 1-6 can be executed in any order before setting TX_FRAME_CTRL.START. Some fields do not need to be reconfigured for every transmission. The frame tag, user data, and frame type are sticky and are retransmitted in the subsequent frame unless modified by software.
Once the frame transmission has started, the TX_FRAME_CTRL.START is cleared by hardware. To monitor if the frame has completed, the software can poll TX_EVT_STS.FRAME_DONE.
