Hi @HBhat2-GRL

You are correct. VCCPGM for 2.5V and below is not supported for AS mode. I stand corrected for my previous answer.

I found a kdb that explains it:

Hi @JwChin ,

Thank you for sharing the kdb. This clears my confusion and it helps me to conclude that for Cyclone V devices, VCCPGM must be connected to either 3.3V or 3.0V for ASx1, ASx4 mode.
