Status Field – Part of each message (async event) from SimpleLink network processor device to the host:
- TxBuff – Indicates the number of available Tx buffers within the SimpleLink network processor device.
- The host can send up to TxBuff packets (<1500 bytes) without waiting for a response from the SimpleLink network processor device.
- The SimpleLink network processor device generates a dummy event if the number is changed (threshold from last update / time-out if change is smaller than the threshold).
