Abstract
The present invention provides a circuit system for data transmission between LPC devices, comprising: a first LPC bus, connected to a first LPC device; a second LPC bus, connected to a second LPC device; and an LPC host controller, able to drive the first LPC device through the first LPC bus and the second LPC device through the second LPC bus; wherein the LPC host controller further comprises an address register. The present invention further provides a method for data transmission between LPC devices, comprising the steps of: starting a first cycle through a first LPC bus by an LPC host controller, wherein a first LPC device sends a request to have a transaction with a second LPC device, and inserting a plurality of wait states after the request is received by the LPC host controller; and starting a second cycle through a second LPC bus by the LPC host controller, wherein the LPC host controller has a transaction with the second LPC device according to the request from the first LPC device.
