How do I clear the CRC error after using the CHANGE_EDREG JTAG instruction to force a CRC error?

To clear the CRC error induced using the CHANGE_EDREG JTAG instruction, you may do one of the following:

1. Using the CHANGE_EDREG JTAG instruction, shift in the original 32-bit CRC value. (Note that the original 32-bit CRC value is shifted out on the TDO pin when you issue the CHANGE_EDREG instruction the first time during error injection)
2. Reconfigure the device from the JTAG port
3. Power cycle the device

Using the CHANGE_EDREG JTAG instruction for fault injection does not affect the device operation. When testing this feature, you can continue the testing after the fault injection procedure without first clearing the CRC error.
