static void ext_pc_int_callback ( void  )

static

Interrupt callback for External PC interrupt Increments the trigger counter when the interrupt is triggered.

Parameters

none

References trigger_count.

Referenced by run_interrupt_trigger_test().

static void run_interrupt_trigger_test ( const struct test_case *  test )

static

Test External interrupt is getting triggered.

This function enables the pin change interrupt(PE0) and changes the status of the pin by outputting high/low on GPIO pin (PE1) which in turn connected to PC interrupt pin

Parameters

test	Current test case.

static void run_set_functions_test ( const struct test_case *  test )

static

Test setting different parameters of the Ext_Int module.

This function calls the different set functions, and verifies that the correct values are being set.

Parameters

test	Current test case.
