ABSTRACT:
A color palette is provided having a plurality input terminals for receiving a plurality of bits of data having an order. A two color path is included which comprises first circuitry coupled to the input terminals for selectively reversing the order of the plurality of bits of data. Second circuitry is coupled to the first circuitry and is operable in a first mode to pass all of the plurality of bits of data received from the first circuitry and in a second mode has at least one word comprising selected ones of the plurality of bits, the selected ones of the bits having a bit order. The third circuitry is provided coupled to the second circuitry and operable to pass all of the bits of data received from the second circuitry in the first mode and operable to selectively reverse the ordering of the selected ones of the bits and pass be at least one word received from the second circuitry in the second mode. The fourth circuitry is further provided coupled to the third circuitry inoperable to receive bits of data passed from the circuitry and select for output as at least one word of true color data at least some of the bits.
