Abstract
The present invention relates to a low latency serial bus system for shadowing registers between first and second digital devices. Either the first device or the second device may initiate a data transfer cycle on the serial bus when data in a shadowed register of that device has changed. The data transfer cycle includes a first frame where data is transferred from the first device to the second device and a second frame where data is transferred from the second device to the first device. The devices do not initiate a subsequent data transfer cycle for changed data if the changed data can be transferred in the current data transfer cycle.
