This section describes how the address map is split into 20 distinct regions.
The CCN-502 has a global address map, that is, every master has the same view of memory. The map is split into 20 distinct memory regions across the 44-bit address space. The decode for each region is determined using a number of CCN-502 inputs that are expected to be static at and beyond the de-assertion of reset. The inputs are SAMADDRMAPx[1:0], where x is an integer from 0-19.
The following figure shows the CCN-502 address map.
