+description: |
+ The Triple Modular Redundancy(TMR) Inject core provides functional fault
+ injection by changing selected MicroBlaze instructions, which provides the
+ possibility to verify that the TMR subsystem error detection and fault
+ recovery logic is working properly.

+ maximum: 255
+ description: |
+ Magic number used when injecting faults. The fault inject write data least
+ significant byte (bits 7:0) must match this number to have any effect.
