25.8.11 ECC Error Status
This register tracks errors on the NVM read path.
ECC error tracking is active until an error is detected. It is still active in case of single error but no dual error. In this case only a dual error can override this register status as a dual error is more critical than a single error. Error tracking resumes as soon as this register is read.

Bits 31:30 – TYPEH[1:0] High Double-Word Error Type
Indicates the type of error detected on the NVM 64-bit most significant read word. It is reset to None when this register is read except if an error occurs in the same cycle.
| Value | Name | Description |
|---|---|---|
| 0x0 | None | No Error Detected Since Last Read |
| 0x1 | Single | At Least One Single Error Detected Since last Read |
| 0x2 | Dual | At Least One Dual Error Detected Since Last Read |
| 0x3 | Reserved |
Bits 29:28 – TYPEL[1:0] Low Double-Word Error Type
Indicates the type of error detected on the NVM 64-bit less significant read word. It is reset to None when this register is read except if an error occurs in the same cycle.
| Value | Name | Description |
|---|---|---|
| 0x0 | None | No Error Detected Since Last Read |
| 0x1 | Single | At Least One Single Error Detected Since last Read |
| 0x2 | Dual | At Least One Dual Error Detected Since Last Read |
| 0x3 | Reserved |
