If an Altera® FPGA features MultiVolt I/O interface capability, can VCCIO be varied dynamically without reconfiguring the Altera® FPGA?

Environment

    Intel® Quartus® Prime Pro Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Altera® FPGAs that feature MultiVolt I/O interface capability, VCCIO must not be varied dynamically or without reconfiguring the device.

 

Resolution

However, the power supply voltage of the Altera® FPGA driving the MultiVolt input may be varied dynamically within limits specified in the Altera® FPGA documentation for the chosen value of VCCIO.
