3.3V CPU providing RST and MD to EM203A and EM100
I intend to embed EM203 and EM100 into my application board. My CPU works at 3.3V.
Can I use I/O lines from my CPU directly to provide RST and MD functionality?
If it's not possible, could I simply switch them LOW through a transistor without a pull-up or a pull-down resistor?
What is the best approach to solve this situation?
