Function Documentation

SelfTest_CAN()

uint8_t SelfTest_CAN	(	CAN_Type *	base,
		const cy_stc_can_config_t *	config,
		cy_stc_can_context_t *	context,
		cy_en_can_test_mode_t	testMode )

This function performs a self-test of the CAN hardware.

It recconfigures the CAN module in the selected loopback mode and transmits test messages. The function verifies if the transmitted messages are received correctly and restores the original configuration.

Note

Do not call this function while the selected CAN instance is handling application bus traffic. The test temporarily reconfigures the CAN block into the requested loopback mode and transmits test messages.

Parameters

base	The pointer to a CAN instance.
config	The pointer to the CAN configuration structure.
context	The pointer to the CAN context structure allocated by the user.
testMode	The test mode to be used for the self-test.

Returns

OK_STATUS (0) - Test passed
ERROR_STATUS (1) - Test failed
