# Generic kernel configuration for PIC32 processor.

|
|
# This file contains all the devices and all the options available

# for the pic32 platform. It's not expected to be buildable, as some

# devices and options are mutually exclusive or incompatible.
|
|
# It's intended to be used as a reference or as a starting point
|
|
# when creating configuration for a new board.
