5. Debugging Functions
(3) Detecting reading from non-initialized areas
If a memory location is read but nothing has been written to that location, the emulator detects “a non-initialized area” and
indicates the error.
To view errors of this type, choose Error Detection Display from the popup menu.
Non-initialized memory locations are shown against a yellow background.
Errors of this type can be detected as exceptional events and used as conditions of hardware breakpoints and trace points (also
refer to “5.14 Detecting Exceptional Events” (page 186)).
(4) Detecting non-inspected areas
If a memory location has been initialized but has not been read, the emulator detects this as “a non-inspected area” and
indicates the error.
To view errors of this type, choose Error Detection Display from the popup menu.
Non-inspected memory locations are shown against a sky blue background.
5.3.2 Setting the Update Interval for RAM Monitoring
Choose Update Interval Setting from the popup menu of the RAM Monitor window. The Update Interval Setting dialog box
shown below will appear.
Figure 5.12 Update Interval Setting dialog box
A separate Update Interval can be specified per RAM Monitor window.
The initial value is 100 ms.
5.3.3 Clearing RAM Monitoring Access History
Choose Access Data Clear from the popup menu of the RAM Monitor window. The history of all access to the RAM
monitoring area will be cleared.
CAUTION
If clearing proceeds while the user program is being executed, the realtime characteristic of execution may be lost because
clearing produces a memory dump.
5.3.4 Clearing RAM Monitoring Error Detection Data
Choose Error Detection Data Clear from the popup menu of the RAM Monitor window. All information on the detected errors
in the RAM monitor area will be cleared.
