 /**

  * @brief   Returns the current value of the system real time counter.

- * @note    This function can be called from any context.

+ * @note    This function is only available if the port layer supports the

+ *          option @p CH_PORT_SUPPORTS_RT.

  *

  * @return              The value of the system realtime counter of

- *                      type rtcnt_t. If the port does not support a

- *                      realtime counter then zero is returned.

+ *                      type rtcnt_t.
