I designed a board with the ADAV4601 on it feeding analog audio into and out of the chip. I am using a USBi eval board to communicate with the ADAV4601 via SigmaStudio. When I drop the ADAV46xx block onto the hardware configuration tab I don't get a Register Controls tab at the bottom. I get a IIC script tab. How am I able to modify the registers of the ADAV4601 without a Register Control tab? When I design a simple schematic to accept analog audio in with a mixer and meter nothing is detected.
Any help would be appreciated.
