Abstract:
1. A display controller driver disposed on one semiconductor substrate and adapted for use with a host device, the display controller driver comprising: a parallel interface adapted to receive data, an address and an endian setting command supplied from the host device, the endian setting command being adapted to set the parallel interface to operate as one of a big endian system or a little endian system; and a command register adapted to store the endian setting command when the address supplied to the parallel interface is matched to an address assigned to the endian setting command, wherein the endian setting command includes a high-order bit portion and a low-order bit portion, the endian setting command having a value that is unchanged with respect to values of specific bit positions even if the high-order bit portion and the low order bit portion of the endian setting command are transposed.
