Hi Folks, There are a few errors in microchip's .INC files for the 16C715, 12C671 and 12C672. The 16C715 is missing the equates for the "MPEEN" config bit. Please these two lines to P16C715.INC: _MPEEN_ON EQU H'3FFF' _MPEEN_OFF EQU H'3F7F' Much more critical is the complete mess made of the 12C671 and 12C672 config word equates. DO NOT use the __CONFIG directive with the values supplied in the files P12C671.INC and P12C672.INC They are hopelessly wrong. I am refering to Version 1.01 files. Come on microchip, these errors are serious. -Jim
