Run MACSC unit tests.

Main function.

The SAM3X_EK, SAM3X Arduino board and SAM4C_EK use two bytes length internal address EEPROM.

static void test_macsc_backoff ( const struct test_case *  test )

static

Backoff slot counter test.

This test starts the backoff slot counter and verifies that the timeout occurs as expected 10 times.

Parameters

test	Current test case.

static void test_macsc_cmp ( const struct test_case *  test )

static

Run MACSC compare test.

This test verifies compare channel functionality for all 3 cmp channels of the macsc and if cmp match occurs after set compare interval

Parameters

test	Current test case.

static void test_macsc_enable ( const struct test_case *  test )

static

Run MACSC enable test.

This test verifies that no timeouts are running after initialization

Parameters
