System Expansion5.1 Expanding your system with additional <strong>Integrator</strong> logic modulesThere are restrictions on how you can expand your system:• Signals on HDRA/HDRB must not clash. Interface modules that use normallyfree bus pins (for example, the IM-AD1 or IM-PD1) cannot be used with the<strong>Integrator</strong>/<strong>CP</strong> because some bus pins are reused for display control.Note<strong>ARM</strong> interface modules such as the IM-PD1 can be used, but some systemfeatures are unavailable. For example, the CLCD and VGA interfaces on both <strong>CP</strong>and IM-PD1 boards use the same set of pins on HDRA for the display controller,but with different pin assignments. Therefore, the VGA/CLCD interfaces on theIM-PD1 would be unusable in this configuration.• Loading for each line is limited (see Chapter 2 Getting Started).• Interrupt assignment is position-dependent on the board organization.• Addressing is position-dependent (see Module-assigned signals on page 3-6).• Inserting the Multi-ICE CONFIG jumper sets the mode for all the boards in thestack. Connect to the top module only.• You cannot add additional <strong>ARM</strong> core modules to the stack.5-2 Copyright © 2002 <strong>ARM</strong> Limited.
