5.1.3 Setting Up the System

On the System page of the Configuration Properties dialog box, specify the configuration of the emulator system as a whole.
During the boot-up process, this dialog box appears after the Device setting dialog box.
Although it is possible to open this dialog box even after the emulator has been booted up, some items will be grayed-out since
they cannot be changed.

(1) Selecting the operating clock
In the Clock section on the System page, select the sources of the clock signals supplied for the main clock and subclock.
The main clock can be selected from among three choices: Emulator, User and Generate (by default, Emulator is selected).
Select Emulator when the main clock is supplied from an internal source and User when the main clock is supplied from an
external source. To use a user-defined clock, select Generate and enter the clock frequency in the text box.
The clock frequency can be set in the range from 1.0 to 99.9 MHz in 0.1-MHz units. The clock frequency for Generate can be
set only once each time the emulator is booted-up.
Subclock options are only selectable for MCUs that support a subclock function. 'Emulator' or 'User' can be selected (by
default, Emulator is selected).
CAUTION
The frequency accuracy for Generate is 5%. Please make sure that final evaluation is performed with a resonator or oscillator
module mounted to generate the actual frequency for use on the target board.
