I can see that there are two different proposals on how to do in-circuit programming of the EEPROM with the ADAU1701.
1) In AN-923 there is just a jumper for grounding the WP pin which is pulled up.
2) On the evaluation board for the ADAU1701 there is a toggle switch performing a similar function (but not the same) of the WP input.
I wonder if there are any special thoughts behind the two different solutions used?
Any pro's and con's? Which one would you recommend?
Is the EVAL-ADUSB2 board using the reset signal when programming the EEPROM?
