... When the ALC658 receives serial data from the AC97 controller, it samples SDATA_OUT on the falling edge of BIT_CLK. When the ALC658 sends serial data to the AC97 controller, it starts to drive SDATA_IN on the rising edge of BIT_CLK. The ALC658 will return any uninstalled bits or registers with 0 for read operations. The ALC658 also stuffs the unimplemented slot or bit with 0’ ...
