We are trying to port the software of MPC8250 to MPC8270. Since, Critical Interrupt Exception (0x00A00)—G2_LE is part of MPC8270 only and not part of MPC8250. I have a question here.
The following events occur when the G2_LE recognizes the assertion of core_cint(Core Critical Interrupt):
- Multi-cycle instructions not in the completion stage are terminated.
- Outstanding load or store instructions that have not been completed are terminated
- Any outstanding page table search activity is terminated
I would like to know what happens if the above events occur in MPC8250? How is it handled as we don't have core_cint signal in MPC8250 G2 core?
Which exception is raised for these events as we don't have critical interrupt exception in MPC8250?
Please share your thoughts.
