# -----------------------------------------------------------------------------
#             LUFA ATPROGRAM Programmer Buildsystem Makefile Module.
# -----------------------------------------------------------------------------
# DESCRIPTION:
#   Provides a set of targets to re-program a device using the Atmel atprogram
#   utility in AVR Studio 5.x and Atmel Studio 6.0 onwards.
# -----------------------------------------------------------------------------
# TARGETS:
#
#    atprogram                 - Program target FLASH with application using
#                                atprogram
#    atprogram-ee              - Program target EEPROM with application data
#                                using atprogram
#
# MANDATORY PARAMETERS:
#
#    MCU                       - Microcontroller device model name
#    TARGET                    - Application name
#
# OPTIONAL PARAMETERS:
#
#    ATPROGRAM_PROGRAMMER      - Name of programming hardware to use
#    ATPROGRAM_INTERFACE       - Name of programming interface to use
#    ATPROGRAM_PORT            - Name of communication port to use
