The MAC address map, as shown in the following table, has been updated to fully memory map all registers and provide the same interface in all cases. Where possible, gaps have been left to allow for future expansion. The Address Map has been split into distinct functional blocks. Each of these blocks is described in more detail in the following sections. For full details of the registers, see Register Space.
