    Abstract: The present invention is to provide a semiconductor device that can correctly switch endians on the outside even if the endian of a parallel interface is not recognized on the outside. The semiconductor device includes a switching circuit and a first register. The switching circuit switches between whether a parallel interface with the outside is to be used as a big endian or a little endian. A first register holds control data of the switching circuit. The switching circuit regards the parallel interface as the little endian when first predetermined control information, that is unchanged in the values of specific bit positions even if its high-order and low-order bit positions are transposed, is supplied to the first register, and regards the parallel interface as the big endian when second predetermined control information, that is unchanged in the values of specific bit positions even if its high-order and low-order bit positions are transposed, is supplied to the first register. Whatever the endian setting status, the control information can be correctly inputted without being influenced by the endian setting status.

    Abstract: A semiconductor device correctly switches endian modes regardless of the current endian mode of an interface. The semiconductor device includes a switching circuit and a first register. The switching circuit switches an interface to be used in big endian or little endian mode. The first register holds control data of the switching circuit. The switching circuit sets the interface in little endian mode when first predetermined control information is supplied to the first register, and sets the interface in big endian mode when second predetermined control information is supplied to the first register. The control information can be correctly inputted without being influenced by the endian setting status.
