(b) Securement of area for debug monitor program
The shaded portions in Figure 3-12 are the areas where the debug monitor program is allocated. The monitor
program performs initialization processing for debug communication interface and RUN or break processing
for the CPU.
program.
[How to secure areas]
It is not necessarily required to secure this area if the user program does not use this area.
To avoid problems that may occur during the debugger startup, however, it is recommended to secure this
area in advance, using the compiler.
The following shows examples for securing the area, using the NEC Electronics compiler CA850.
assemble source file and link directive code, as shown below.
• Assemble source (Add the following code as an assemble source file.)
• Link directive (Add the following code to the link directive file.)
-- Secures 2 KB space for monitor ROM section

-- Secures interrupt vector for debugging
.section

-- Secures interrupt vector for serial communication
-- Change the section name according to serial communication mode used

The following shows an example when the internal ROM end address is 0x3ffff and internal RAM end
address is 0x3ffefff.
