- * '''External peripherals''': Accesses use virtual addresses if the MMU (Memory management Unit) is activated, or physical addresses if it is not. In this case, the physical address is computed as pbase = SEG_XXX_BASE + cluster_io << 32.
+ * '''External peripherals''': All accesses use virtual addresses if the MMU (Memory management Unit) is activated, or physical addresses if it is not. In this case, the physical address is computed as pbase = SEG_XXX_BASE + cluster_io << 32.
 
- * '''Internal peripherals''': Accesses use virtual addresses, and the MMU must be activated. The peripheral virtual base address is computed as vbase = SEG_XXX_BASE + cluster_xy * PERI_CLUSTER_INCREMENT.

 The SEG_XXX_BASE , X_IO, Y_IO, and PERI_CLUSTER_INCREMENT variables must be defined in the ''hard_config.h" file.
