//Next step, reduce the resource consumed

//version 0.5, defined many parameter to configure the IP core, making it easier to use.

//version 0.3, create this file to be a common included one for future use to config the IP core

//This file used to define some macro-varibles which can be used by all other files

//NOTE!!! Olny one of the following two definitions can be open

`define frameIDfromRx                   //frameID comes from Rxmodule

//`define frameIDcount                  //frameID counts for itself by adding one every frame
