(4) CAN global automatic block transmission delay setting 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.
After reset: 00H
Cautions 1. Do not change the contents of the C0GMABTD register while the ABTTRG bit
