Software Introduction:
-
1. Provides rich library functions and powerful integrated development debugging tools, with a full Windows interface.
-
2. Completes the entire development process including editing, compiling, linking, debugging, and simulation.
-
3. Developers can edit C or assembly source files using the IDE itself or other editors.
-
4. The map file can be generated by LIB51 to create library files, or it can be linked with library files through L51 to generate absolute target files (.abs).
-
5. The emulator is equipped with an 11.0592MHz crystal oscillator, but users can replace it with other frequency oscillators in the emulator’s oscillator socket.
-
6. The reset button on the emulator only resets the emulation chip and does not reset the target system.
-
7. The 31st pin (/EA) of the emulation chip is connected to a high level, so only the internal ROM can be used during emulation, and external ROM cannot be used; however, the 31st pin in the external connector of the emulator is not connected to the 31st pin of the emulation chip, so this emulator can still be inserted into a target system that has external ROM (with its CPU’s /EA pin connected to a low level).
