SpiceLogic Inc. offers a tool for learning Hex Code of INTEL 8051 family 8 bit microcontrollers. This program will parse the hex code byte by byte data with addresses and Disassemble the code. After that, it will show you the complete CODE memory map, the way your object code will reside in the code memory. It will help you to realize the exact picture about how your instruction set will stay physically in the code memory. INTEL's 8051 family 8 bit Microcontrollers can access at most 64KB of code memory. So, this software is limited to only '16 bit address' data records. Not good for Extended Segment Address Record or Extended Linear Address Record.
