Initialize the USART for unit test.

Initializes the SERCOM USART (SERCOM4) used for sending the unit test status to the computer via the EDBG CDC gateway.

int main

(

void

)

Run RTC unit tests.

Initializes the system and serial output, then sets up the RTC unit test suite and runs it.

static void run_rtc_count_test ( const struct test_case *  test )

static

Test for RTC count polled mode test.

This test initializes the RTC module and checks whether the initialization is successful or not.

Then this test executes compare_match test and overflow test.

Parameters

test	Current test case.
