ERR<n>PFGCDN | Jon's Arm Reference

This register is present only when error record n is implemented, the node that owns error record n implements the Common Fault Injection Model Extension and error record n is the first error record in the node. Otherwise, direct accesses to ERR<n>PFGCDN are RES0.

Countdown value.

This field is copied to Error Generation Counter when either:

Software writes 1 to ERR<n>PFGCTL.CDNEN.
The Error Generation Counter decrements to zero and ERR<n>PFGCTL.R is 1.

While ERR<n>PFGCTL.CDNEN is 1 and the Error Generation Counter is nonzero, the counter decrements by 1 for each cycle at an IMPLEMENTATION DEFINED clock rate. When the counter reaches zero, one of the errors enabled in the ERR<n>PFGCTL register is generated.

Note

The current Error Generation Counter value is not visible to software.

The reset behavior of this field is:

On a Cold reset, this field resets to an architecturally UNKNOWN value.
