Can the DHCP snooping learn new entries while the static binding entry reaches the limit?

DHCP snooping and static binding use the same entry table. When one of them reaches the limits, the other one cannot learn/set new entries.
This means when static binding entries reach the limit, DHCP snooping cannot learn new entries.

For example: 

If the maximum limit of entries is 512  for the IP Source Guard feature.
When you configure 512 static IP-MAC bindings, the device will not be able to learn any new addresses through DHCP snooping,
