Run IOPORT unit tests.

Main function.

Initializes the clock system, board and serial output, then sets up the IOPORT Service unit test suite and runs it.

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

static void run_ioport_pin_test ( const struct test_case *  test )

static

Test IOPORT pin level is getting changed.

This function set the direction of CONF_OUT_PIN to output mode with pull-up enabled and read the status of pin using CONF_IN_PIN which is configured in input mode.

The pin CONF_OUT_PIN and CONF_IN_PIN are shorted using a jumper.

Parameters

test	Current test case.

static void run_ioport_port_test ( const struct test_case *  test )

static

Test IOPORT port level is getting changed.

This function set the direction of CONF_PORT_OUT_PIN_MASK to output mode with pull-up enabled and read the status of pin using CONF_PORT_IN_PIN_MASK which is configured in input mode. The pin CONF_PORT_OUT_PIN_MASK and CONF_PORT_IN_PIN_MASK are shorted using a jumper.

Parameters

test	Current test case.
