NOTE: This document is strictly an external reference specification for the 2 7114B card. It only specifies what is seen and observable at its interface points: the CIO backplane and the parallel frontplane interface. For more information as how it operates in a system, the readers must confer with other documents: HP-CIO Standard Document, the respective driver's ERS etc ... Contrary to the expectation of some readers, this document is not intended to be used as an ERS for the GPIO product which consists of both a hardware (card) and a software (driver) product. As a product, some of the card's behaviors will be greatly influenced by how the driver is written. That kind of information is to be covered in another document which describes the hardware/software interaction. It is assumed that the reader is familiar with the CIO standard (HP-CIO STANDARD DOCUMENT, Version 2.2 - Roseville Networks Division).
