A liquid crystal device is sequentially illuminated with three primary color lights in three primary color illumination steps including an off period before, before and after and after the primary color light period, respectively. A preferred embodiment of the invention uses a generic, or highly adaptable, hardware device. When the receiving end receives a packet of isochronous transfer type with an incorrect header, the receiving end does not send a retry signal to the transmitting end. The noise suppression scheme permits an all digital PLL to operate in such a way to avoid generating the spurs that would normally be generated from the injection pulling effect of interfering sources on the chip. In another embodiment, a system controller monitors commands and addresses and inserts no operation commands to prevent such collision of data and addresses.
