The Parallel I/O protocol function is incorporated into the Test Instrumentation section category of the IBPD System and is accessed through the System Devices on the main menu.   The Parallel I/O has two hardware interface functions, a CPU I/O type byte port with three separate device select lines with separate read / write lines and dual 16 bit byte controlled parallel ports.  The Parallel I/O interface allows the user to control a variety of data transfer functions.  The block diagram below shows the hardware interface parallel I/O and the standard Push Terminal Block (PTB-50).  Custom interconnects are available which allow FPGA's or CPLD's to interface to the users "Unit Under Test" and are available as an option.   Technical support is also available for the user to build their own custom interface.  The advantage of a custom interface is that it may be stored and reused to reduce the setup errors and store in the users database custom software protocols that will be used for communications for the custom interface.

The Parallel I/O Protocol also includes the standard CLADS and programming debug dialogs as other protocols.  The device programming dialogs pertain to the CPU I/O port only for dialog controlled programming.  All Command Line Arguments for initiating either the CPU I/O or the 16 Bit Byte controlled digital I/O are available.  This allows the user to use the ports for programming, data transfer and parallel FLASH chip programming.

The dual 16 Bit Byte Controlled Digital I/O is a standard multiple function digital I/O. It may operate as a simple latched output only, a direct sense input or a single port BUS I/O with separate Read / Write lines.  When using the dual 16 bit Byte controlled I/O in BUS mode you get four byte ports that are independently programmable via Command Line Arguments when used in the command mode.   The dialog limits the operation of the ports to manual only.   The CPU type I/O port however may be used to transfer a byte file in both manual Dialog mode and background CLA command mode.
