Hi All,

I want to learn about the advantages of XBAR in MPC5643L. Why we need crossbar for controller?As we have interrupt priority in other controllers like MC9S12XE and MC9S12XHY, why there is need for master slave concept?Also I heard that it is enough to have default configuration for XBAR in MPC5643L. Then what is there to do with XBAR? I didnt get these things? Is crossbar switch is advangeous for MPC5643L? I need the exact answers for the above questions.
