• To modify the value of each read or write type, change the value of the associated
spin box.
• The lowest possible value is 0.
• The highest possible value is 127.
• To store changes into the currently selected memory block, click the OK button. The
Access Details dialog box disappears, and the system clears the Auto Configure
checkbox.
• To abandon your changes, click the Cancel button. The Access Details dialog box
disappears and the system discards your changes.
• To bring up appropriate help information, click the Help button.

You can save the current memory configuration into the file you defined at the outset.
Clock Frequency Setup
The Full Chip Simulation provides a true time information. It is possible to provide an
oscillator clock frequency to the debugger. The debugger CPU awareness and IO modules
provide the "clock factor" to apply to this input frequency to derive the CPU cycle
frequency.
Figure 28.8 Clock Frequency Setup Dialog Box
Derivative-specific IO simulations which require bus speed change information (multiply
or divide) from the PLL modules update the clock factor while the application simulation
is running.
This does not affect the accumulated elapsed time, and applies a new cycle time to the
next simulated instructions in real time.
Open the Clock Frequency Setup dialog (Simulator > Clock Frequency) to set, enter, or
edit either the oscillator frequency or the CPU frequency. However, the saved project
