(CRC32, CRC16 and CRC8). The FCE interrupt is enabled to report execution errors. Any CRC kernel calculation error is indicated by switching ON the related LED. 2019-10-17 Copyright © Infineon Technologies AG 2019.

Hardware setup This code example has been developed for the board KIT_AURIX_TC297_TFT_BC-Step. 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved. - Page 5 FCE Error Interrupt Service Routine The ISR will be executed in case of a CRC calculation error. It will scan all kernels status registers and check if error flags are set. 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved.
- Page 6 In the setup phase, the port pins of the LEDs have to be configured as push- pull output using the function IfxPort_setPinMode(). If CRC calculation errors occur, the related LEDs are switched on using the function IfxPort_setPinLow(). 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved.
- Page 7 Run and Test After code compilation and flashing the device, observe the LEDs’ behavior. All LEDs (1) should be switched Off if all CRC algorithms calculation are correct (Result = Expected) 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved.
