DESCRIPTION
Ceibo FE-51RD2 is a development tool that supports ATMEL W&M
89C51RD2 microcontrollers at any frequency allowed by the devices. It is
serially linked to a PC or compatible systems and can emulate the
microcontrollers using any clock. Emulation is carried out by loading the
system with the user software and an embedded monitor program. FE-
51RD2 locates the monitor in the upper 4K of the code memory space,
together with the ISP routines. The system uses standard devices for real-
time and transparent emulation. The emulator is not frequency or voltage
restricted, so it can be used to emulate the microcontroller in the complete
range of parameters defined by the device. Three working modes are
available: real-time, in-circuit simulation and simulator. In the real-time mode
the user software is executed transparently and without interfering with the
microcontroller speed. Breakpoints can be added to stop program execution
at a specific address. The in-circuit simulation is used to provide a trace
function by slowing down the emulation speed; instructions are executed by
the simulator, except the peripheral related instructions. The simulation is
intended only for software debugging of the basic 8051 functions. FE-51RD2
may be disconnected while using the simulation mode. The software
includes C and Assembler Source Level Debugger, On-line Assembler and
Disassembler, a limited C Compiler and many other features. The system is
supplied with MS-Windows debugger software, RS-232 cable power supply,
mechanical adapters and other accessories.
SPECIFICATIONS
SYSTEM MEMORY
FE-51RD2 provides 64K of code memory. However, only 60K are available
embedded monitor program that uses the upper 4K of the memory space.
Code memory is mapped as belonging to the FE-51RD2 Emulator.
BREAKPOINTS
Breakpoints allow real-time program execution until an opcode is executed at
a specified address.
WINDOWS DEBUGGER
The FE-51RD2 software includes a source level debugger for Assembler and
high-level languages C and others) with the capability of executing lines of
the program while displaying the state of any variable. The debugger uses
symbols contained in the absolute file generated by the most commonly used
Assemblers and High Level Language Compilers. The CEIBO Windows
Debugger runs only under Windows 98 or later and also under Windows NT.
