11 / 82 page ADT7462 www.onsemi.com 11 Configuration Option 2 Configuration Option 2 is used for thermal monitoring and fan control for Processor 1 and Processor 2 in a dual processor system. It can also monitor one set of VIDs, if required. Features of Configuration Option 2 include the following: • One Local and Three Remote Thermal Channels • Up to Four PWM Drives and Up to Eight TACH Inputs (VID Pins and TACHs/PWMs are Muxed Together) • Two THERM I/Os • Two VRD Inputs • RESET I/O • Two VCCP Voltage Monitoring Channels Figure 20 shows the pin configuration when Configuration Option 2 is chosen.
