XSemNpiStatus - NPI Status structure to store the data read from PMC RAM registers. This structure provides:
- NPI scan status information (Refer XSem_CmdNpiGetStatus API)
- NPI descriptor slave skip counter value if arbitration fails
- NPI scan counter value
- NPI heartbeat counter value
- NPI scan error information if SHA mismatch is detected
Declaration
typedef struct
{
u32 Status,
u32 SlvSkipCnt[MAX_NPI_SLV_SKIP_CNT],

} XSemNpiStatus;| Member | Description |
|---|---|
| Status | NPI scan status |
| SlvSkipCnt | Slave Skip Count: Contains the number of times NPI scan failed to get arbitration for GT/DDRMC descriptor |
| ScanCnt | NPI Scan Count: Increments each time NPI scan successfully completes a full scan (Including the first scan) |
| HbCnt | Heart Beat Count: Increments for each slave group scanned in the descriptor and each time SHA is calculated |
| ErrInfo | Error Information: Is updated with error details in case of SHA mismatch failure. -ErrInfo[0]: Calculated SHA value of the descriptor for which mismatch is observed. -ErrInfo[1]: Bit[31:16] Reserved. Bit[15:8] The descriptor index number for which the SHA failure is observed. Bit[7:0] The skip count index of the descriptor where SHA failure is observed (This value is zero if arbitration is not applicable for the descriptor) |
