CnGMABTD - CANn global automatic block transmission delay register
The CnGMABTD 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.

Do not change the contents of the CnGMABTD register while the ABTTRG
bit is set to 1.
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.
