1.4.1. Fault Injection Register

The EDERROR_INJECT JTAG instruction controls the contents of the JTAG fault injection register. The register holds the information of the error that you want to inject into the configuration memory.

You can scan the location of the error or errors into the 21-bit (46-bit for Arria® V, Cyclone® V, and Stratix® V devices) JTAG fault injection register at any time. The contents of the JTAG fault injection register is loaded into the fault injection register when the last and first data frame is being processed. In other words, you can only inject the error into the first frame of the configuration data but you can monitor the error information at any time.ister holds the information of the error that you want to inject into the configuration memory.

Note: The contents of the fault injection register are cleared when zero bits are loaded into the fault injection register from the JTAG fault injection register.
