Title: Internal Memory vs. Data Memory
Post by: Joel Moore on February 12, 2004, 07:40:12 PM

Other than the bit-size is there any significant difference between using the built-in internal memory variables (A thru Z) and data memory (DM[1], etc)?  Is the internal memory faster?

There is no difference since both DMs and A to Z are residing on the same RAM area. DMs are 16-bit data so they may load a little faster but the time saving is insignificant.
