16   CoreSight components are compliant with the ARM CoreSight architecture
23   The CoreSight Address Translation Unit (CATU) translates addresses between an
24   AXI master and system memory. The CATU is normally used along with the TMC to
25   implement scattering of virtual trace buffers in physical memory. The CATU
27   non-contiguous Physical Addresses (PAs) that are intended for system memory.
