Just a quick question. I see several references to setting up the WDTCSR register in the following way:
WDTCSR = (1<<WDE) | (1<<WDP2); //250msec timeout
But I can't find any header files where the registers are defined - neither in AVRStudio4 or CodeVisionAVR. Where can I find the definitions for these registers? I can of course write them myself, based on the chip datasheet. But if the definitions is already part of some package I haven't installed, then it would be a bit redundant.
