Retrieves the J-PORT enumeration table. This returns the number of peripherals and their IDs.
Exceptionally, the sent packet has no header. The first byte carries the number of peripherals on the
list. All the others carry a peripheral ID or 0. The first byte will be 0 if no enumeration is present.
