3.3.2. JTAG Device Configuration
To configure a single device in a JTAG chain, the programming software sets the other devices to bypass mode. A device in 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.
You can configure the Intel® Agilex™ device through JTAG using a download cable or a microprocessor.
