Bit 27 – PFMDED Flash Double-bit Error Detected (DED) Status bit
0’) in
software.| Value | Description |
|---|---|
| 1 | A DED error has occurred |
| 0 |
A DED error has not occurred |
Bit 26 – PFMSEC Flash Single-bit Error Corrected (SEC) Status bit
Note: The PCACHE interrupt event
reports the error event to the CPU. See Nested Vector
Interrupt Controller (NVIC) from Related Links.
| Value | Description |
|---|---|
| 1 |
A SEC error occurred when PFMSECCNT[7:0] equals to zero |
| 0 |
A SEC error has not occurred |
Bits 7:0 – PFMSECCNT[7:0] Flash SEC Count bits
1’ each time an SEC error occurs. Holds at zero. When an SEC
error occurs when PFMSECCNT[7:0] is zero, the PFMSEC status bit is set. If PFMSECEN
is also set, a prefetch module interrupt event is generated.
