PIC32MX
2.3
The PIC32MX core supports three modes of operation:
user mode, kernel mode, and debug mode. User mode
is most often used for applications programs. Kernel
mode is typically used for handling exceptions and
operating system kernel functions, including CP0
management and I/O device accesses. An additional
Debug mode is used during system bring-up and
software
specification for more information on debug mode.
