  * @attention 1. This API should be called after esp_wifi_start() and before esp_wifi_stop()
  * @attention 2. When device is in STA mode, this API should not be called when STA is scanning or connecting to an external AP
-  * @attention 3. When device is in softAP mode, this API should not be called when softAP has connected to external STAs
-  * @attention 4. When device is in STA+softAP mode, this API should not be called when in the scenarios described above
+  * @attention 3. When device is in softAP mode and has connected to external STAs, it initiates the CSA process
+  * @attention 4. When device is in STA+softAP mode, this API should not be called when STA is scanning or connecting to an external AP
+  *               or softAP has connected to external STAs.
  * @attention 5. The channel info set by this API will not be stored in NVS. So If you want to remember the channel used before WiFi stop,
  *               you need to call this API again after WiFi start, or you can call `esp_wifi_set_config()` to store the channel info in NVS.
+  * @attention 6. When operating in 5 GHz band, the second channel is automatically determined by the primary channel according to the 802.11 standard.
  *
  * @param     primary  for HT20, primary is the channel number, for HT40, primary is the primary channel
  * @param     second   for HT20, second is ignored, for HT40, second is the second channel
