  * - Tasmota v14.0.0
  * - GVRelease 1.5.2
- * - Function pinmode is reduced implemented by GPIOViewerVueApplication
+ * - Function pinmode is not fully implemented by gpio_viewer_1_5:
  *   Only INPUT_PULLUP and INPUT_PULLDOWN are reported as INPUT
  *   Only OUTPUT and OUTPUT_OPEN_DRAIN are reported as OUTPUT
  *   All other pin modes are reported as UNKNOWN
  * - This driver is forcing INPUT_PULLUP for ANALOG and INPUT
