Abstract
The present invention provides methods and modules allowing for mapping of interface signals at for instance multi-line buses. A mapping of internal signal order schemes to external signal order schemes is enabled such that upon configuration any interface signals may carried on any lines of a multi-line bus. The configurability may obtained by the implementation of mapping logics and mapping algorithms, which associates external interface terminal to signal association to internal interface terminal to signal association in a configurable manner.
