Hello all, I am new to this. So sorry for the stupid question. Once I write a program to the PIC12C672, If I want to change the program and load it, Do I erase it, or Write over the old Program? I know if it was Flash, I would goes use a software erase command. Thanks, Joseph Thorman -- http://www.piclist.com hint: The PICList is archived three different ways.
