RTEMS CPU Architecture Supplement
An RTEMS based application is initiated or re-initiated when the PowerPC processor is reset. The PowerPC architecture defines a Reset Exception, but leaves the details of the CPU state as implementation specific. Please refer to the User's Manual for the CPU model in question.
In general, at power-up the PowerPC begin execution at address 0xFFF00100 in supervisor mode with all exceptions disabled. For soft resets, the CPU will vector to either 0xFFF00100 or 0x00000100 depending upon the setting of the Exception Prefix bit in the MSR. If during a soft reset, a Machine Check Exception occurs, then the CPU may execute a hard reset.
