Two-Wire Interface Having Dynamically Adjustable Data Fields Depending On Operation Code

摘要

The present invention-to-gereonti operating at this time is determined to be performed on the slave component (120 121 122), the master component 110 sends at least a portion of the frame to the slave component (120 121 122) over the data wire 132 It relates to a wire 131 and 132 interface. Master component 110 repeating such detection and transmitted each time determines that the operation depending on whether the same components as the slave component or other slave component a communication previously performed on the slave component (120 121 122) do. Frame structure itself, may vary according to the operation performed. For example, one frame may also include an extended address data field including address information to extend past the base address field contained in another frame. A frame, on the other hand to (cyclic redundancy check field, the response message field, and / or fields such as an error) including a field confidence, may not include another frame having a different operation. ; To-wire interface, the master component, the slave component, cyclic redundancy check
