I use PK51 package (C51, LX51) and trying to locate "Silicon Lab" F8051F321 MCU internal memory code according to the following: (1) Few C files ranging 0x00-0x7FF with the main() function in address 0x00. (2) Library located at address 0x800. (3) Few other C files should be located within the range of 0x1600-0x3BFF while one of these function should be located at address 0x1600. Spent two days in reading the manuals and trying various solutions but nothing worked. Please advice !
