18.104.22.168.1. Pin Connections and Guidelines
Observe the following pin connections and guidelines for this configuration setup:
- Tie the following pins of all devices in the chain together:
By tying the CONF_DONE and nSTATUS pins together, the devices initialize and enter user mode at the same time. If any device in the chain detects an error, configuration stops for the entire chain and you must reconfigure all the devices. For example, if the first device in the chain flags an error on the nSTATUS pin, it resets the chain by pulling its nSTATUS pin low.
- If you are configuring the devices in the chain using the same configuration data, the devices must be of the same package and density.
