Hi
I am reading about the Infineon C167CS-LM microprocessor.
Could anyone tell me what an Open Drain Control Register does? What is the purpose of this register?

It controls the output mode of the I/O pins: push/pull or open drain.
That is it's purpose as well.
The user's manual discribes this very clearly, complete with simplified schematics of a push/pull and a open drain output driver. See chapter "7.2 Output Driver Control" of the 167CS user's manual.
