# RTC

## Overview

The RTC demo provides the following features:
- Set RTC time
- Read RTC time
- Set RTC Alarm
- Set RTC Alarm interrupt
- Enable rentention mode for Battery domain

## Board Setting

No special settings are required

## Running the example

When the example runs successfully, the demo will shoe the menu on the console UART port as below:

```console
---------------------------------------------------------------------------
*                                                                         *
*                                   RTC Demo                              *
*                                                                         *
*       1. Show RTC time                                                  *
*       2. Demonstrate 3 types of RTC alarm                               *
*       3. Demonstrate the retention mode of Battery Domain               *
*       4. Set RTC Time                                                   *
*       5. Demonstrate RTC interrupt                                      *
*                                                                         *
---------------------------------------------------------------------------
```

Type one of the listed option to run corresponding example.

## NOTE
- Example #3 will reset the SoC, so it is better to run it with `flash_xip` or `flash_sdram_xip` related builds for better user experience
