12.1.2.3 The debugger for 740
Only the ROM area memory-mapped in the area set as Internal can be designated for software
breakpoint.
You cannot set software breakpoint in ROM areas memory-mapped in the SFR area, RAM area or
other areas set as External.
12.1.3 Get or set C variables
•
If a variable is declared with the same name as the type definition name declared by typedef, you
cannot reference that variable.
•
Values cannot be changed for register variables.
•
Values cannot be changed for 64 bit width variables (long long, double, and so on).
•
Values cannot be changed for C/C++ expressions that do not indicate the memory address and
size.
•
For the sake of optimization, the C compiler may place different variables at the same address. In
this case, values of the C variable may not be displayed correctly.
•
Literal character strings can only be substituted for char array and char pointer type variables.
•
No arithmetic operations can be performed on floating point types.
•
No sign inversion can be performed on floating point types.
•
Casting cannot be performed on floating point types.
•
Casting cannot be performed on register variables.
•
Casting cannot be performed on structure types, union types, or pointer types to structure or
union types.
•
Character constants and literal character strings cannot contain escape sequences.
•
The following values can be substituted for the bit-fields.
-
integer constants, character constants, and enumerators
-
variables of bool types, characters types, integers types, and enumeration types
-
bit-field
When the substituted value is larger than the size of the bit-field, it will be truncated.
•
The bit-field member allocated in the SFR area might not be transformed into a correct value.
•
While the target program is running, values of local variables and bit-fields cannot be modified.
