CHAPTER2 Dependence Functions
Target program size
CODE XX(KB)
DATA YY(KB)
Required RAM space (MB) = 20 + (XX / 64) 6 + (YY / 64) 1.5
However, RAM space larger than the above may be needed depending on program allocation. Allocate
memory space consecutive areas should be reserved as much as possible.
Example: Program with 1 MB of CODE and DATA sizes
Required RAM space (MB) = 20 + (1024 / 64) 6 + (1024 / 64) 1 / 5 = 140MB
■ Simulation Range
The simulator debugger simulates the MCU operations (instruction operations, memory space, interrupts,
reset, low power consumption mode, etc.) Peripheral I/Os, such as a timer, DMAC and serial I/O, other
than the CPU core of the actual chip are not supported as peripheral resources. I/O space to which
peripheral I/Os are connected is treated as memory space. There is a method for simulating interrupts like
timer interrupts, and data input to memory like I/O ports. For details, refer to the sections concerning I/O
port simulation and interrupt simulation.
• Instruction simulation
• Memory simulation
• I/O port simulation (Input port)
• I/O port simulation (Output port)
• Interrupt simulation
• Reset simulation
• Low power consumption mode simulation
