• Manufacturer Part Number: pic32mx320f064h
• Description: 64/100-pin General Purpose, 32-bit Flash Microcontrollers
• Manufacturer: Microchip Technology Inc.

6.3
There are two modes of operation of the PIC32MX
core: User mode and Kernel mode. To support these
modes, the virtual address space is also divided into
two segments, kernel segments and user segments.
The lower 2 GBytes of virtual addresses form the User
mode partition, and the upper 2 GBytes forms the
Kernel mode partition.
Most application will run only in Kernel mode. For
these applications, the entire program can reside in the
kernel address space providing full access to all
resources.
