Unit: Data bit time (DBT)
1.
Do not change the contents of the CnGMABTD register while the ABTTRG
bit is set to 1.
2.
The timing at which the ABT message is actually transmitted onto the CAN
bus differs depending on the status of transmission from the other station or
how a request to transmit a message other than an ABT message (message
buffers 8 to 31) is made.
