Hi,
Please make connections as following:
Depends on your VIN level, the pull-up resistor for NRST should be selected to make sure the final level on the pin should be >1.8V and < 3.3V based on its built-in 1.2M OHm pulldown resistance. Same consideration apples to your on/off control signal EN1; it's should be >1.8V and < 3.3V based on its built-in 0.5M OHm pulldown resistance.
Please let's know if you have further questions.
