TI JTAG programming protocol

[Binome]

Hi,
I'm trying to understand TI JTAG programming protocol.
I've a Stellaris LM3S2965 board and I'd like to create my own programmer but I don't know what JTAG instructions (and when) I have to send. Someone told me it's documented but I don't find anything on the web.
Do someone know where I can find it?
Thanks.

Did you review the documents at arm.com?

No, I've searched on ti.com because I thought I had to understand the board before the chip. I'm wrong?

I presume that Stellaris JTAG protocol is based on general Arm specifications which can be found at arm.com. It might be docmented at TI, too.

I'm searching but I don't find a document to precisely tell the procedure...
