We are building a PCB using the G120 chip, and got a question about the LDR0 and LDR1 pins.
Can I safely join the two pins together, let them float (no pullup to high) ?
And when I would need to upgrade the firmware, I ground them both together (using a pushbutton switch for example)?
The reason why is that we just want to expose a single switch outside the enclosure when a firmware update is necessary.
I already tested the method and it works with the G120HDR, but just want to confirm if it’s an OK solution or if it’s hack that may or may not work in the future.
