PIC32MX Memory Layout

The PIC32MX microcontrollers implement two address spaces: 

virtual and physical. 

All  hardware  resources,  such  as  program  memory,  data  memory  and  peripherals,  are  located  at  their  respective 

physical addresses. Peripherals, such as DMA and Flash controllers, use physical addresses and access memory 

independently of the CPU. 

Virtual addresses are exclusively used by the CPU to fetch and execute instructions. Virtual address space can be 

thought as CPU’s logical view and use of its physical resources.

A graphical representation of the PIC32MX virtual and physical memory is shown in picture below:
