- * This bitmask allows to specify multiple channels for changing flight modes using
- * momentary buttons. Each channel is assigned to a mode slot ((lowest channel = slot 1).
- * The resulting modes for each slot X is defined by the COM_FLTMODEX parameters.
- * The functionality can be used only if RC_MAP_FLTMODE is disabled.
+ * This bitmask allows to specify multiple channels to indicate whether it's a button.
+ * If not marked, the channel is assumed to be a switch. This configuration allows the
+ * rc_update to correctly decode the input signals to trigger appropriate actions.
  *
- * The maximum number of available slots and hence bits set in the mask is 6.
