The STAC9758/ 9759 can support up to 5 GPIOs. The STAC9758/9759 implementation of internal jack sense uses the Extended Paging Registers defined by the AC '97 Specification. This allows for additional registry space to hold the identification information about the CODEC, the jack sensing details and results, and the external surroundings of the CODEC. The information within the Extended Paging Registers will allow for the automatic configuration of the audio subsystem without end-user intervention. For example, the BIOS can populate the Extended Paging Registers with valuable information for both the audio driver and the operating system such as gain and attenuation stages, input population and input phase and jack location. With this input information, the IDT driver will automatically provide to the Volume Control Panel only the volume sliders that are implemented in the system, thus improving the end-user's experience with the PC. The information in the Extended Paging Registers will also allow for automatic configuration of microphone inputs, the ability to switch between SPDIF and analog outputs, the routing of the master volume slider to the proper physical output, and SoftEQ configurations. The fully parametric IDT SoftEQ can be initiated upon jack insertion and removal. The STAC9758/9759 is designed primarily to support 6-channel audio. Additionally, the STAC9758/ 9759 provides for a stereo enhancement feature, IDT Surround 3D SS3D .
