# MCU - What a mess.  IAR uses different mechanisms for C and ASM
# and buggers the identifier for the mega parts so the GCCMCU will break
# with mega parts.  The AVRXMCU goes away when IAR updates their tools for
# unified IO headers (ioavr.h)  NB: IAR Also needs the linker files changed too.

# MCU = 8515, 8535, mega103, mega163, etc (C compiler input)
# AAVRMCU = 0, 1, 2, ...
# GCCMCU = at90s8535, atmega103, etc
# AVRXMCU = (see define) - matches what ICCAVR will pass in the future...
