Description
Yes. The JTAG TCK pull-down resistor value is incorrectly specified as 10k-ohms in the Stratix® and Cyclone® devices Configuration chapters. The correct external pull-down resistor value is 1k-ohm. This stronger resistor ensures that the TCK signal is biased at a logic low level despite the weak internal pull-up on this pin. The internal pull-up ranges from 20k-ohms to 40k-ohms across process, voltage and temperature.
Future versions of the Stratix and Cyclone Handbooks will be updated accordingly.
