• Characteristics of Uncorrectable Errors − Impact the functionality of the interface − No mechanism defined in the specification to correct these errors − Reporting an uncorrectable error is similar to asserting SERR# in PCI/PCI-X • Further Classification of Uncorrectable Errors − Fatal Errors Errors cause the particular link and related hardware unreliable Reset of the component on the lank may be required How to handle is platform implementation specific − Non-Fatal Errors Errors cause a particular transaction to be unreliable But the link is otherwise fully functional This classification provides related HW or SW an opportunity to recover the error without resetting the components on the link and disturbing other transactions in progress TM 19 Freescale, the Freescale logo, AltiVec, C-5, CodeTEST, CodeWarrior, ColdFire, ColdFire+, C-Ware, the Energy Efficient Solutions logo, Kinetis, mobileGT, PowerQUICC, Processor Expert, QorIQ, Qorivva, StarCore, Symphony and VortiQa are trademarks of Freescale Semiconductor, Inc., Reg.
