15 The LPC bus is a means to bridge a host CPU to a number of low-bandwidth
17 primary use case of the Aspeed LPC controller is as a slave on the bus
21 The LPC controller is represented as a multi-function device to account for the

13 The Aspeed BMC SoCs typically use the Keyboard-Controller-Style (KCS)
14 interfaces on the LPC bus for in-band IPMI communication with their host.
