Hello
I'm having the following problem while implementing the MPC5777C based test code.
- Enable SWT A and read NCF of FCCU, fault 14 (SWTRS0) is recorded.
- Tried NFC 14 fault Clear (SWA A disabled and NCF Clear), but the fault still occurs.
Regarding this phenomenon, I have two questions.
1. Under what conditions can the FCCU NCF14 fault (SWTRS0) of the MPC5777C occur?
2. What should I do to clear the FCCU NCF14 fault (SWTRS0) of MPC5777C?
I look forward to your reply.
Thank you
Hello,
Well this is a bit tricky as the SWT holds line to FCCU (not a toggle).
So any clearing of FCCU status will have effect like 1 clock cycle and then it is already set back since fault line from SWT is still active.
As Reference manual express. Clear first status inside SWT.
Under what conditions can the FCCU NCF14 fault (SWTRS0) of the MPC5777C occur?
The condition is SWT_A reset as explained below:
Best regards,
Peter
