1.3 Links and LEDs
The interface module provides one link and one LED. These are the CONFIG link and
CONFIG LED.
Fitting the CONFIG link places all of the modules in the stack on which the interface
module is mounted into CONFIG mode. This mode enables you to reprogram the FPGA
image in the configuration flash on the logic module(s) using Multi-ICE (see the user
guide for the logic module).
The CONFIG LED lights to indicate when the stack is in CONFIG mode.
