The ERR<n>PFGCTL characteristics are:
Enables controlled fault generation.
This register is present only when error record <n> is implemented, the node implements the Common Fault Injection Model Extension (ERR<n>FR.INJ != 0b00) and error record <n> is the first error record owned by a node. Otherwise, direct accesses to ERR<n>PFGCTL are RES0.
ERR<n>FR describes the features implemented by the node.
ERR<n>PFGCTL is a 64-bit register.
