    摘要: An integrated circuit (IC) includes an output driver circuit portion that is electrically configurable, via a configuration input, to operate in either a first mode or a second mode corresponding to an indication of a condition of the IC, such as a supply voltage indication, the first mode and the second mode having different drive characteristics. A configuration interface circuit portion as part of the improved IC is adapted to selectively override the configuration input to configure operation of the output driver circuit portion in either the first mode or the second mode based on a drive strength control input, regardless of the condition of the IC.

    摘要: An electronic product includes an application specific semiconductor chip (ASIC) device which includes in its circuitry both a linear regulator module configured to be coupled to an optional external capacitance and a capless regulator module configured to be coupled to internal capacitance of the electronic product. Control logic of the ASIC device is responsive to a regulator selection signal for selecting one of the linear regulator module and the capless regulator module for use in powering the ASIC device. The control logic may select the linear regulator module for certain times of operation and the capless regulator module for other times of operation.

    摘要: A network interface device includes a random access memory used as a transmit and receive buffer for transmission and reception of data between a host computer bus and a packet switched network. The network interface device includes a memory controller that determines whether a complete frame is stored in the random access memory and also determines an amount of data available to be read from the oldest received frame. A host CPU is able to access this information and determine whether to read the data or read the data at a later time.

    摘要: A network interface device includes a random access memory used as a transmit and receive buffer for transmission and reception of data frames between a host computer bus and a packet switched network. The network interface device includes read and write controllers for each of the transmit and receive buffers, where each write controller operates in a clock domain separate from the corresponding read controller. The memory management unit also includes a synchronization circuit that controls arbitration for accessing the random access memory between the read and write controllers. The synchronization circuit determines the presence of a stored frame in the random access memory by asynchronously comparing write counter and read counter values stored in gray code counters, where each counter is configured for changing a single bit of a counter value in response to an increment signal. The determined presence of one or more stored data frames is used to arbitrate storage of tracking information by either the read controller or the write controller into a holding register used to determine a read status for the random access memory.

    摘要: A multi-interface integrated circuit in which, during the chip's lifetime in use, only one interface is active at a time. However, special test logic powers up all of the on-chip interface modules at once, so that a complete test cycle can be performed. All of the interfaces are exercised in one test program. Since some pads are inactive in some interface modes, mask bits are used to select which pads are monitored during which test cycles.

    摘要: A network interface includes a multiplexer that selectively supplies either a stored address from an address holding register, or a reload address from a reload address holding register, to a random access buffer memory based on a done delay signal (DMA_DONE_DLY). The done delay signal is generated by an advance signal generator in response to detection of a target initiated termination request on the PCI bus during a DMA data transfer from the random access buffer memory to the target. if the PCI bus transfer is interrupted, the reload address is supplied to the random access buffer memory to enable data output holding registers to be reloaded with the data lost by the target during the interrupted DMA transfer. The array of data output holding registers are capable of recovering from the interrupted PCI bus transfer and output the data set which the target (e.g., the host system memory) expects to receive. The reload address is also supplied to the address register to resume normal addressing by address holding register.
