Test capture and compare.

This test uses TCC0 as a PWM generator (compare function). TCC1 will be set to capture the signal from TCC0 to test the capture functionality.

Parameters
testCurrent test case.

Test Non-Recoverable Fault (FAULTx)

This test uses TCC0 as a PWM generator (compare function). EXTINT will be used to route fault input to TCC0.

Parameters
testCurrent test case.

static void run_init_test ( const struct test_case test)
static

Test of tcc_init() and tcc_get_config_defaults()

This test is used to initialize the tccx_module structs and associate the given hw module with the struct. This test should be run at the very beginning of testing as other tests depend on the result of this test.

static void run_reset_test ( const struct test_case test)
static

Test initializing and resetting TCC and reinitialize.

This test tests the software reset of a TCC by the use of the tcc_reset().

Parameters
testCurrent test case.
