Flash is usually more plentiful than RAM Often the CRC is not the bottleneck (not this version anyway!)
Confirms my thought that Flash/Rom/Const lookup is going to be fine unless you have a high end PIC (> 1K RAM) and *REALLY* need a few clocks more. > > Speed: a constant array lookup requires 9 clocks; a variable array lookup > requires 5 clocks.
