transmitted/received through Ethernet
[Description]
The control register is used to set the data to be accessed through Ethernet. The maximum capacity is
1024 bytes.
Sending data: After users write a data length data into CR#064, and data into CR#65, DVP-FPMC
will automatically clear values in the two control registers to 0.
Receiving data: Users read the contents of CR#066 first, and then read the data in CR#067.
CR#070: Node ID of an SDO server
