• Types of the Correctable Errors − Bad TLP (bad LCRC or incorrect Sequencer Number) − Bad DLLP − Replay Timer Timeout − Replay Number Rollover − Receiver Error (for example, Framing error) • Characteristics of the Correctable Errors − Automatic HW recovery action, no software intervention − Performance will degrade − No information loss − Normally software does not need to monitor TM 16 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.

• Example 1: 1) Sender sends a TLP (Transaction Layer Packet) over the link 2) Recipient receives a Bad TLP with bad LCRC due to link signal integrity 3) Recipient’s DLL detects the Bad TLP and discards it 4) Recipient sends a NAK DLLP to sender 5) Sender HW automatically resends (Retry or Replay) the same TLP • Example 2: 1) Sender sends a TLP (Transaction Layer Packet) over the link 2) Recipient never acknowledges the packet (no ACK is returned to sender) 3) Sender’s Replay Timer expires 4) Sender resends the same TLP and logs the Replay Timer Timeout error status TM 17 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.
