CHAPTER 16: DEBUGGER
16.9.4 Displaying and Modifying Memory Data and Register
The db33 has functions to operate on the memory and registers. Each memory area is set to the debugger
according to the map information that is given in a parameter file. Memory access and data display in half word
or word units are performed in little-endian format by default. It can be changed so that the specified area will be
accessed in big-endian format using the parameter file.
Operating on memory area
300
(1) Dumping data memory
(2) Entering/modifying data
(3) Rewriting a specified area
(4) Copying a specified area
(5) Monitoring memory
Following operations can be performed on the memory area:
Memory contents are displayed in hexadecimal and ASCII characters. If [Memory] windows are open, the
content of the [Memory] window at the top is updated. If no [Memory] windows are open, memory contents
are displayed in the [Command] window. (db, dh, dw commands).
The display start address and the display format (byte, halfword, or word) of the [Memory] window can be
changed from the popup menu that is brought up by right-clicking somewhere in the window. (Refer to
Section 16.4.4, "[Memory] Window".)
The data at a specified address is rewritten by entering hexadecimal data. (eb, eh and ew commands)
Data can be entered or modified in the [Memory] window as well (see Section 16.4.4).
An entire specified area is rewritten with specified data. (fb, fh and fw commands)
The content of a specified area is copied to another area. (mv, mvh and mvw commands)
Four memory locations, each with area to store a word (4 bytes), can be
registered as watch data addresses. The registered watch data can be
verified in the [Register] window. When operating in ICE mode, the
content of this window is updated in real time at 1 to 0.1-second intervals
by enabling the on-the-fly function. Addresses 0, 4, 8, and C are made the
watch data addresses by default.
Note that data of the internal RAM area is not updated in real time since
accesses to the internal RAM area cannot be detected from outside the
chip. It will be updated after the target program breaks.
