When I design my circuit, I'm confused and made the wrong connection. I connected my microprocessor to second pin instead of third pin of cyrstal. But I left the third pin blank. So when my circuit come from manufacturer, I can solder pins 2 and 3 and problem fix. Is this solution to work ? According to datasheet second pin must connect to ground.
This is datasheet. https://www.mouser.com.tr/datasheet/2/905/c_NX3225SA_e-1317523.pdf
And my circuit.
*Capacitors connected to second pin.
You can short 2 & 3.
However I would check if 2 is not connected to the case. In that case I would prefer to remove the connection of 2 and the CPU.
Pins 2 and 4 are connected to the crystal case. You will need to cut the trace to pin 2 and reconnect it to pin 3. That should work until you can fix the board layout.
For sure you will need to isolate pin 2 unfortunately. The case adds too much parasitic capacitance. Normally the case is grounded, you should also include this when you roll the layout.
