Cyclone III Device JTAG Configuration
The JTAG configuration scheme uses the IEEE Standard 1149.1 JTAG interface pins, and supports the JAMTM Standard Test and Programming Language (STAPL) standard. Cyclone® III devices are designed such that JTAG instructions have precedence over any device configuration mode. Therefore, JTAG configuration can take place without waiting for other configuration modes to complete. JTAG configuration can be performed using an Altera® download cable or an intelligent host such as a microprocessor.
Configuration methods in JTAG mode include:
- Using a download cable for in-system programmability (ISP) and prototyping
For more information, please refer to the Configuring Cyclone III Devices chapter of the Configuration Handbook.
