18.104.22.168. JTAG Single-Device Configuration
To configure a single device in a JTAG chain, the programming software sets the other devices to bypass mode. A device in a bypass mode transfers the programming data from the TDI pin to the TDO pin through a single bypass register. The configuration data is available on the TDO pin one clock cycle later.
The Quartus® Prime Pro Edition software can use the CONF_DONE pin to verify the completion of the configuration process through the JTAG port:
- CONF_DONE pin is low—indicates that configuration has failed.
- CONF_DONE pin is high—indicates that configuration was successful.
After the configuration data is transmitted serially using the JTAG TDI port, the TCK port is clocked an additional 1,222 cycles to perform device initialization.
