p3041 reset platform clock frequency

We are trying to get the CPU to read the RCW during boot. On the P3041, If the SYSCLK input is 83.3 Mhz, what will be the Platform Clock frequency and the subsequent ELBC clock frequency when the processor reads the RCW from NOR flash. Since the PLLs are not up at that time. The P3041RM is vague on how the platform clock and/or the ELBC clock behave during reset while reading the RCW from NOR. We are seeing an approximate 5Mhz ELBC clock while reading the RCW.

 

secondly, is there any errata regarding booting from 32 bit flash? When we boot with the codewarrior tap, we can read and write the flash properly so it seems to be interfaced correctly. We have programmed the RCW in flash and it is correct by inspection with codwarrior.
