TMS320F28335: Code Security Module.....

Part Number: TMS320F28335
Other Parts Discussed in Thread: UNIFLASH, C2000WARE

I am using CCS 8.3.1 and an XDS110 with a custom board.  I have read a lot of good information about the code security module but I am really not sure procedurally how to use it there must be a description somewhere.  What are the steps?  

I have my production code ready and want to be able to lock the part before shipping the hardware but i want to try it out:

- How do i set the password - if the answer is ccs i dont see the "on-chip flash" option under tools

- I want to verify it is locked

- I want to try getting back into it in case i need to make a change

- can i set the password back to all 1 to get back to development if needed

- what code do i need in my application?  i have CsmUnlock() from the example not sure it is run though, do i need it or is the key read as part of bootloader?

Any help would be appreciated.  Thanks!
