Abstract:
A data processing system comprising:a first supply voltage;a second supply voltage;a bus;a plurality of slave devices coupled in parallel to said bus, each of said slave devices having a slave bus transceiver for transmitting and receiving signals on said bus; anda master device coupled in parallel to said bus, said master device having a master bus transceiver for transmitting and receiving signals on said bus, wherein signals transmitted from said slave bus transceiver to said master bus transceiver vary over a first voltage range which is less than the difference between said first supply voltage and said second supply voltage, and signals transmitted from said master bus transceiver to said slave bus transceiver vary over a second voltage range which is approximately equal to the difference between said first supply voltage and said second supply voltage.
