Regarding disconnection detection between ADIN2111 and ADIN1110

Question

Is the following method correct for detecting a disconnection between the ADIN2111 and ADIN1110 using the ADIN2111? 
 Q1: Generate an interrupt when the link state changes. Q2: How often do you check the link state?(How long does it take to detect a link down?) Q3: Can you detect early signs of a disconnection by monitoring the MSE?

Hi Uboti 
 Thank you for your patience, here are our answers 
 Q1. I am glad you found your answer on this, you can also rely on the AN_LINK_STATUS to check the link. 
 Q2. The approximate times that the link takes to be down when the cable is disconnected varies depending on the device role in the link: 
 
 Leader: link is dropped after 75 ms 
 Follower : link is dropped after 100 ms 
 
 The above times are measured from the moment a the linking partner is disconnected to the time when LINK_ST goes low. 
 When the cable is connected again, it takes between a few hundred milliseconds to a couple of seconds depending on the level of training of the signal. 
 Q3. MSE cannot be used to detect the early signs of disconnection, the MSE register is relying on the link status register first to acquire that data, however that stage rely on the link up which only detect if the cable is connected or not.
