Hi,can I switch the voltage one(one of four) bank(for example, from 3.3V to 2.5V or 1.8V) during the operation of the device when the device is energized(supply voltage on vccint and voltage to all vccio bank except one is applied)?
Hi,we have not tested or support this method. You can refer the power up sequence requirement from user guide. You can try with own risk. Why can't you switch off and change the vccio. If you change the vccio when the device is energized, which will pause/stop the operation for a few micro second.
