I would like to interface an AD7764 to a McASP port (McBSP ports unavailable). However, the AD7764 is a single-channel device. The AD7764 will produce clock, data, and frame signals as shown in Figure 2 in their datasheet (http://www.analog.com/static/imported-files/data_sheets/AD7764.pdf). It seems like it ought to work, but the frame pulse produced by the AD7764 lasts for all 32 bits of the transmitted word. Can the McASP port deal with such a long frame pulse? I think that as long as the frame pulse starts at the correct time, its length is not important, but I haven't been able to find anything definitive in the various manuals.
