The CnGMABTD register is used to set the time interval at which packet buffer data is allocated to
ABT and transmitted in ABT normal operating mode.

Note 1 When ABTTRG is 1, do not change the contents of cngMABTD.
2. The time at which ABT packets are actually transmitted to the CAN bus varies depending
on the status of the transmission from other workstations or the way in which ABT packets
(packet buffers 8 to 15) are requested to be transmitted.
