Manufacturer:Cirrus Logic Description:Enable pin for the Boot ROM or an external register. Pin has an internal 5 k O pull-up resistor. Bus command and byte enable are multiplexed on the same PCI pins. These bits provide the bus command during the address phase of the transaction. They provide the byte enable during the data phase. Byte enable determines which byte lines carry valid data. Bit 0 coincides with byte 0. Bit 1 coincides with byte 1, etc. Indicates that the driving device has decoded its address as the target of the current access. As an input, determines whether a device on the bus has been selected. The IA21140AF bus master asserts this signal to indicate the beginning and duration of a bus transaction access. Data transfer continues while this signal is asserted. Deasserting this signal indicates the transaction is in the final phase. These pins can be configured by software to perform either input or output functions for system specific applications. |
