* @brief TestPurpose: verify RTC internal counter enable/disable/read work
* @details
* - Test Steps
* -# Enable RTC internal counter
* -# Read RTC internal counter and sleep for a while
* -# Read RTC internal counter again and compare it with the previous value
* -# Disable RTC internal counter and repeat previous operations
* - Expected Results
* -# When enabled, the values read from RTC internal counter increase.
* -# When disabled, the values read from RTC internal counter don't change.
