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.
