当在 HWA_CONFIG 寄存器中检测到奇偶校验不匹配时，会发生 X FSM 配置奇偶校验错误。以下步骤列出了有关如何注入 X FSM 配置奇偶校验错误的程序。

1. HWAOPEN 指令用于在启用奇偶校验计算和启用奇偶校验 (PARITYCTRL = NORMAL) 的情况下，写入 HWA_CONFIG 和 HWA_OFFSET，也可使用 Get_MMAconfig() 中提到的参数来配置 HWA_CONFIG。

2. 在要进行测试的特定字段 (X FSM)，软件会损坏向量寄存器中的数据值。

3. 在禁用奇偶校验计算并启用奇偶校验 (PARITYCTRL = PNCMCK) 的情况下，HWAOPEN 指令再次用于使用来自该 C7x 向量寄存器的损坏数据写入 HWA_CONFIG 和 HWA_OFFSET。在此模式下，将根据受影响寄存器中使用时计算出的奇偶校验值，检查最初计算并保存的奇偶校验值。
4. 执行 HWAXFER 以注入错误。错误会在 HWA_STATUS 寄存器中更新。

5. 执行 HWARCV 指令以观察错误。
