After the first device completes configuration in a multi-device configuration chain,
its nCEO pin drives low to activate the nCE pin of the second device, which prompts
the second device to begin configuration. Therefore, if these devices are also in a JTAG
chain, ensure that the nCE pins are connected to GND during JTAG configuration or
that the devices are JTAG configured in the same order as the configuration chain. As
long as the devices are JTAG configured in the same order as the multi-device
configuration chain, the nCEO pin of the previous device drives the nCE pin of the
next device low when it has successfully been JTAG configured. You can place other
Altera devices that have JTAG support in the same JTAG chain for device
programming and configuration.
JTAG configuration allows an unlimited number of Cyclone III device family to be
cascaded in a JTAG chain.
For more information about configuring multiple Altera devices in the same
configuration chain, refer to the
volume 2 of the Configuration Handbook.
