(4) CAN0 global automatic block transmission delay register (C0GMABTD)
The C0GMABTD register is used to set the interval at which the data of the message buffer assigned to ABT is to
be transmitted in the normal operation mode with ABT.

Cautions 1. Do not change the contents of the C0GMABTD 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.
3. Be sure to set bits 4 to 7 to “0”.
