When using multiple devices at the same time, it is necessary to initialize
each device and obtain a different ID.
Execute functions by specifying the ID of each device. At the time of termination,
perform termination processing for each device.
Here is an example of using multiple devices.
Use two CAN-4P-PE and one CAN-4PF-PE, and
each device is set to the following device name.
The variables that store the ID of each device are ID_CAN1, ID_CAN2, ID_CANFD1.
CAN-4P-PE 1st: CAN000
CAN-4P-PE 2nd: CAN001
CAN-4PF-PE : CAN002
