  Description:  HAL interface for the MSP430FET/CC2400EB combination referred to in
                AN033. The Hardware Abstraction Library is a collection of functions,
                macros and constants, which can be used to ease access to the
                hardware on the CC2420 and the target microcontroller.

                This file contains all definitions that are specific for the
                MSP-FET430P140 development board.
