µVision2 Monitor Debugger

Keil's Monitor is available in three versions: MON166, MON251 and MON51.

The Monitor is a full-featured, license-free, royalty-free target monitor designed for the specific microcontroller family.  It may be configured for a wide variety of target systems including those with a bootstrap loader. The Monitor communicates with the µVision2 Debugger using your PC's COM port. You may use the µVision2 Debugger and the Monitor to easily debug your target programs in real-time. You can view program symbols, debug using your source code, watch program variables, examine memory contents, and more!

Hardware Requirements

• 5 Kbytes code space
• 256 bytes of data memory
• 10 bytes of stack space in the user program
• Serial port for the PC interface
• NMI or other TRAP for breakpoints on MON166
• Serial interrupt for MON51 and MON251
