4.0
PIC32MX3XX/4XX microcontrollers provide 4 GB of
unified virtual memory address space. All memory
regions including program, data memory, SFRs and
Configuration registers reside in this address space at
their respective unique addresses. The program and
data memories can be optionally partitioned into user
and kernel memories. In addition, the data memory can
be made executable, allowing PIC32MX3XX/4XX to
execute from data memory.

4.2
PIC32MX3XX/4XX 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. Virtual addresses are exclusively used by
the CPU to fetch and execute instructions as well as
access peripherals. Physical addresses are used by
peripherals such as DMA and Flash controller that
access memory independently of CPU.
