Description
Since there is no minimum DCLK frequency specification for EPCS and EPCQ configuration devices, it is possible to use a very low frequency clock, an intermittent clock, or a clock whose frequency varies for DCLK provided other EPCS or EPCQ device timing parameters are not violated.
The only exception is when using EPCS128 devices manufactured before 2012, with a 65nm fabrication code. For further details on this, see the related solution.
