  Any suggestion about how to use the methods for writing data in FLASH memory on a PIC 18F2480 and its special function for the 64 bytes block minimum requirement?

Isaac Marino Bavaresco Says: " I wrote an assembly 'memcpy' routine for use with Hi-Tech PICC Compiler/Assembler. It was tested and work OK, but may have bugs yet. " +
