System Monitor for the 8051
Specifications
8051 Compatible
Allows for development and debug of user software
Extensive command set
Build-in Single Line Assembler/Diassembler
In a typical development setup, a host computer (PC or compatible) is serially linked to the 8051 hardware. A cross assembler or cross compiler on the host generates object code for the application. The host then assumes the role of terminal via terminal emulation software. This allows the user to send commands to, and to view responses from the MD-51 system monitor. In particular, generated object code can be downloaded to the 8051 board. MD-51 commands are then sent to execute and test out the downloaded code.

MD-51 command entry is line oriented to allow simple line editting prior to command processing. MD-51 display information can be suspended, resumed, and aborted. Standard 8051 interrupt service routines are routed through external RAM for flexibility. (Note that some interrupt service entry points on the 80C320 and 87C550 are not compatible with the 8051.)
