Write protect on the AD5233 digital potentiometer

Question asked by ricker on Nov 29, 2017

I'm using the AD5233 with two chips daisy chained using the SDO pin. Can you tell me why is it required to send a NOP instruction after taking WP from low to high? What can happen if the NOP instruction is not sent? Also the data sheet does not give any timing information related to the WP signal. Is there some timing requirement that must be met regarding the WP pin?
