1. MCAN wrong message transmission
■ Problem Definition
There is a possibility a message with an ID (arbitration field) and a format and DLC (control field) is transmitted which was
not configured by the application. The message itself is syntactically correct and can be received by other nodes.
The occurrence of the limitation requires a certain relationship in time between a transmission request for sending a
message and the coincidence of noise in the 3rd bit of intermission field which is treated as the start of new message
transmission (SoF).
■ Trigger Condition
Under the following conditions a message with wrong ID, format and DLC is transmitted:
•
M_CAN is in state "Receiver" (PSR.ACT = "10"), no pending transmission.
•
A new transmission is requested after sample point of 2nd bit of intermission but before the 3rd bit of
Intermission is reached.
•
The CAN bus is sampled dominant at the third bit of Intermission which is treated as SoF (see ISO11898-1:2015
Section 10.4.2.2).
■ Scope of Impact
Under the conditions listed above it may happen, that:
•
The shift register is not loaded with ID, format, and DLC of the requested message.
•
The M_CAN will start arbitration with wrong ID, format, and DLC.
