Chapter 1 Introducing the CIO-DIO48H Overview: CIO-DIO48H features The CIO-DIO48H provides 48-bits of digital I/O. The I/O is organized into two 24-bit groups based on an 82C55 mode 0 emulation. Each 24-bit group is divided into three eight-bit ports labeled An, Bn and Cn, where n is either "1" for FIRSTPORT or "2" for SECONDPORT. Port C can be split into two four-bit nibbles — Port C-HI and Port C-LO. Each of these ports may be individually programmed as input or output. All digital in

Chapter 3 Functional Details 82C55 emulation The CIO-DIO48H emulates the 82C55 chip. The 82C55 emulation initializes all ports as inputs on power-up and reset. A TTL input is a high impedance input. If you connect another TTL input device to the output, it could be turned on or off every time the board is reset. To establish a consistent TTL level at power-up, use resistors tied to either +5V (pull-up) or ground (pull- down). There are open locations for pull-up and pull-down resistor p
