Is it possible for GIO output level lower than 3.3V like 2.5 or 1.8V of BF 548(EZ-kit Lit)?
I am using GPIOs of BF548 EZ-kit to control external multiplexers to switch channels. I would like GPIO output level lower than 3.3V in logic 1(2.5V/1.8V) due to lower voltage level controls on multiplexers may reduce charges during switching (this is very important for my project).
Could you please advise me what & how to change BF548 GPIO logic level in software or hardware settings on BF548 EZ-kit lit?
Many Thanks in advance.
