This error occurs when a LCRC verification fails or with a sequence number
error.
This error occurs when a CRC verification fails.
This error occurs when the replay timer times out.
This error occurs when the replay number rolls over.
This error occurs when a sequence number specified by the

●
A training error occurs when the MegaCore function exits to LTSSM
detect state from any state other than the following: hot reset, disable,
loopback, or L2.
