uhh. Depends on what sync level your setting your value and rate at.
8 bit's of information is 0 to 255 and is often INT in nature(ie no decimal value)
16 bit is apx 65k and can also handle decimle.
If your using on the lesser data values/rates at 8 bit. then that's what will happen. SI u;n guessing your using
So i'm guesing your using Low(int, 2bytes).
first it's an INT. No decimals.
I'm als going to assume that C2 use of 2bytes is -255 to 255 rather than 0 to 255 for 1byte.
