A method for providing more than one function to pins of a programmable device used in a server system includes the programmable device and first and second devices. The programmable device is electrically connected to the first device and the second device. The programmable device includes a major logic communication device, a detection module, a storage module, and at least one multiplexing pin. The second device is powered on, sending an in-position signal to the detection module through the at least one multiplexing pin.

A method for providing a high-speed data communication between a host and field-programmable gate array (“FPGA”) is disclosed. The method, in one embodiment, is capable of identifying a data rate on a bus containing a P-channel and an N-channel operable to transmit signals in accordance with a high-speed Universal Serial Bus (“USB”) protocol. Upon sampling, by a first input deserializer, first two samples of data signals carried by the P-channel in accordance with a first clock signals clocking twice as fast as the data rate of the P-channel, a second input deserializer is used to sample the second two samples of data signals transmitted by the N-channel in accordance with a second clock signal running twice as fast as the data rate of the N-channel with a ninety (90) degree phase shift. The method subsequently forwards the data signals to one or more configurable logic blocks (“LBs”) in FPGA.

During a charge collection time frame charge collected on each of the summing bit lines from current flowing in the programmable Vt transistor is summed. During a pulse generating time frame digital pulses are generated having pulse widths proportional to the amount of charge that was collected on each summing bit line during the charge collection time frame.

A CAN bus transmitter has an input to receive a transmit data signal, and CANH and CANL outputs coupled to a CAN bus. The CAN bus transmitter comprises a plurality of CAN driver circuits having inputs coupled through delay circuits with their CANH and CANL outputs in common and connected to the CAN bus.

Variable delaying of the input logic level changes to each of the plurality of CAN driver circuits reduces emission of unwanted signals from the CAN bus.
