Hi, Has anyone translated the assembly code for Analog Devices EE191 "Implementing a Glueless UART Using the Sharc DSP SPorts" from it's ADSP-21161 to the newer ADSP-21262 and ADSP21363? The SPort interrupt registers changed with the part change. Before I re-wrote it, I thought I'd see if anyone had one they felt like sharing.

Hi all, I got the transmit and receive portions to work with help from a couple of newsgroup replies. My project is for a custom board, with different dai pins from the eval board, and it's a vdk project using the ADSP21262, so it won't just be a drop in for you. It might be help anyway so I'm sending it along. I'm not sending the complete project, just the parts about the UART. Let me know
