ABSTRACT:
The present invention provides an easy access ports structure. In accordance with the present invention, each port has a register bank. Each register bank has the same address. A global register is used in the present invention to store the status values. When operating, the CPU accesses one port in accordance with the application program. The status values of the other ports are mapped to the global register. Therefore, the CPU also can understand the other ports status through the global register when accessing one port.
