Parity Error Injection (PARITY_ERR_INJ) – Offset d590
The errors are injected by flipping the parity bits before they are checked by the parity checker.
This allows it to check the parity checking and error reporting mechanism inside the IBECC.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:21 | 0h | RO | Reserved |
| 20:19 | 0h | RW/V | Read Completion Header Parity Flip Enables (RD_HDR_ERR_EN) Per flit control to invert parity on next incoming read completion header in order to test error reporting mechanism. Auto cleared by HW after parity flip take |
| 18:11 | 0h | RW/V | Read Completion Data Parity Flip Enables (RD_DATA_ERR_EN) 1 control bit per data parity bit being generated; If set to 1, the corresponding data parity bit received for the next transaction will be inverted; This bit will be cleared to 1b0 by HW after a transaction has been received with a parity error. |
| 10:9 | 0h | RW/V | Write Request Header Parity Flip Enable (WR_HDR_ERR_EN) Per flit control to invert parity on next incoming write request header in order to test error reporting mechanism. Auto cleared by HW after parity flip take |
| 8 | 0h | RW/V | Read Request Address Header Parity Flip Enable (RD_ADDR_ERR_EN) Control to invert parity on next incoming read request address in order to test error reporting mechanism. Auto cleared by HW after parity flip takes place |
| 7:0 | 0h | RW/V | Write Request Data Parity Flip Enables (WR_DATA_ERR_EN) 1 control bit per data parity bit being generated; If set to 1, the corresponding data parity bit received for the next transaction will be inverted; This bit will be cleared to 1'b0 by HW after a transaction has been received with a parity error. |
