Problem with float operations
I checked another machine with a reasonably new IAR version (4.something) installed. Almost all of the libs in both clib and dlib folders had either a _mul or a _nomul suffix.

Lee, are you sure? Quote: -- 0xff is read back into R24 Doesn't the code actually read DDRC back to R24? And since the top two bits of DDRC are zero despite the previous write to...
