- * this parameter is NULL, the screen will be blanked out, and this function will disable the
- * SLCD peripheral for additional power savings. If the message is non-NULL, it will replace

- * of the string with spaces if you wish for the message to appear on line 2, i.e. " SLEEP").
- * Also note that this function will NOT clear any indicator segments that you have set. This is
- * by design, in case you wish to leave an indicator lit in sleep mode.
+ * @param display_on if true, leaves the LCD on to display whatever content was on-screen. If false, disables

* @details This shallow sleep mode is not the lowest power mode available (see watch_enter_deep_sleep), but
* it has the benefit of retaining your application state and being able to wake from the ALARM button.
* It also provides an option for displaying a message to the user when asleep. Note that whether you
