I am going to use a MicroSD card on my carrier card without a write protect switch, so I want to ensure I wire it correctly. This is my question.
The documentation seems to indicate that SDCARD_WP is active high, not active low (by the naming convention without a “#”). If I want to write protect my SD card, should SDCARD_WP pulled high or low. I am thinking it should be pulled low to write protect, since there is a pullup on the TX1 module.
