摘要: Integrated pointing device and integrated keyboard inputs are accepted at a microcontroller that formats the to HID protocol embeds formatted into SMBus messages for transfer over an processing components of information handling system. A state machine system motherboard extracts packets from provides registers use by components. Keyboard communicated devices through may be treated as trusted data separate non-trusted external buses.
