The PLL_ENA pin and the configuration input pins
dual buffer design: a 3.3-V/2.5-V input buffer and a 1.8-V/1.5-V input
buffer. The VCCSEL input pin selects which input buffer is used. The 3.3-
V/2.5-V input buffer is powered by V
buffer is powered by V
VCCSEL is sampled during power-up. Therefore, the VCCSEL setting
cannot change on the fly or during a reconfiguration. The VCCSEL input
buffer is powered by V
A logic high VCCSEL connection selects the 1.8-V/1.5-V input buffer, and
a logic low selects the 3.3-V/2.5-V input buffer. VCCSEL should be set to
comply with the logic levels driven out of the configuration device or
MAX
If you need to support configuration input voltages of 3.3 V/2.5 V, you
should set the VCCSEL to a logic low; you can set the V
bank that contains the configuration inputs to any supported voltage. If
