Functions
uint8_t	SelfTest_CANFD (CANFD_Type *base, uint32_t chan, const cy_stc_canfd_config_t *config, cy_stc_canfd_context_t *context, cy_stc_canfd_test_mode_t test_mode)
	This function configure the CANFD channel in an internal loopback and then it is configure to accept message IDs in the range 0x50 to 0x55 and a message with message ID 0x60 is transmitted and RX fifo is verified to be empty.

Function Documentation

SelfTest_CANFD()

uint8_t SelfTest_CANFD	(	CANFD_Type *	base,
		uint32_t	chan,
		const cy_stc_canfd_config_t *	config,
		cy_stc_canfd_context_t *	context,
		cy_stc_canfd_test_mode_t	test_mode )

This function configure the CANFD channel in an internal loopback and then it is configure to accept message IDs in the range 0x50 to 0x55 and a message with message ID 0x60 is transmitted and RX fifo is verified to be empty.

Similarly, a message with message ID 0x50 is transmitted and the message received in RX FIFO is verified.

Note

Do not call this function while the selected CAN FD channel is handling application bus traffic. Internal test mode keeps the test inside the CAN FD block; external test mode also drives the external CAN FD pins.

Parameters

base	The pointer to a CAN FD instance
chan	The CAN FD channel number
config	The pointer to the CAN FD configuration structure
context	The pointer to the context structure allocated by the user. The structure is used during the CAN FD operation for internal configuration and data retention. The user must not modify anything in this structure.
test_mode	internal: will not drive the pin external: will drive the external pins along with loopback

Returns

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