Page 5: Chapter 1: Introduction
Chapter 1: Introduction The PCIe-DIO-24HC is a x1 lane PCI Express (PCIe) board designed for use in a variety of Digital I/O (DIO) applications. It uses the high speed PCIe bus to transfer digital data to and from the board. The board includes a single 8255 chip and three 82C54 Counter/Timers making it easy to program. - Page 6 OUT2 of the first 82C54 if the IRQT jumper is installed. All interrupt trigger sources can be individually selected through software. When triggered, an interrupt is requested. Figure 1-1: Block Diagram Manual PCIe-DIO-24HC PCI Express Digital I/O w/CTR...

1. There are two 8-bit groups (A and B) and two 4-bit groups (C Hi and C Lo). 2. Any port can be configured as an input or an output. 3. Outputs are latched. 4. Inputs are not latched. Manual PCIe-DIO-24HC PCI Express Digital I/O w/CTR... - Page 14 D7 is also latched in a buffer controller for the associated PPI chip. A high state disables the buffers and, thus, all four buffers will be put in the tristate mode; i.e. disabled. Manual PCIe-DIO-24HC PCI Express Digital I/O w/CTR...
