I'm currently routing a board using the LPC4330FBD144 (eg. LQFP144 package).
I've almost finished connecting the SD card by now, but it seems there's no SD_WP pin on the LQFP144 version.

Do I just pick any GPIO pin to look at the WP pin ?
How will the controller handle a 'missing' SD_WP pin; is there a way that I can make sure it doesn't write when it's not allowed to ?


Love
