21.2.5 Overload frame
1040
An overload frame is transmitted under the following conditions.
• When the receiving node has not completed the reception operation
• If a dominant level is detected at the first two bits during intermission
• If a dominant level is detected at the last bit (7th bit) of the end of frame or at the last bit (8th bit) of the error
delimiter/overload delimiter
Note In this CAN controller, all reception frames can be loaded without outputting an overload frame because

Outputs 6 dominant-level bits consecutively.
The node that received an overload flag in the interframe space
outputs an overload flag.
Outputs 8 recessive-level bits consecutively.
If a dominant level is detected at the 8th bit, an overload frame
is transmitted from the next bit.
Output following an end of frame, error delimiter, or overload
delimiter.
An interframe space or overload frame starts from here.
