I have a Teensy 4.1 I am using on a project. I am having trouble detecting the removal of a SD card while the program is running. I notice the Hirose SD card socket has a card detect switch and I have verified it works with an ohmmeter. One side is connected to ground (left side) but the right side does not seem to go to any of the pins exposed on the Teensy board. Does the card detect pin connect to any port on the processor or do I need to solder it to an unused port pin on the Teensy board?
Thanks in advance for your help.
