Hi rkavinash03,

Sorry for the inconvenience we bring you!
This is a known issue of ProcessorExpert of CodeWarrior. You may select MKE02Z32xxx4 PEx cpu component. Or use KDS3.2 instead of CodeWarrior.

Note the trimming. The KEAZN32 and KE02Z32 devices ship from the factory with factory trim to 32MHz. To get the part operating at 40MHz requires the internal clock source ICS to have *user* trim (to 39.0625 kHz (upper limit)). Normally this user trim is written into flash at 0x0000_03FF/03FE and must be copied into the ICS_C3 register by the startup code. Simply setting the PEx CPU component ‘Slow internal reference clock [kHz]’ to 39.0625 does not make the clock 40MHz. 

Best Regards,
Robin
