(2) Internal high-speed oscillation clock

This method uses the clock inside the emulator by configuring the use of the high-speed oscillation clock in the

user program.

(3) Internal low-speed oscillation clock

This method uses the clock inside the emulator by configuring the use of the low-speed oscillation clock in the

user program.

(4) Subsystem clock

The clock settings are listed below.

Table 2-3.

Settings for Subsystem Clock

Type of Clock to Be Used

(a) When the clock generated within the emulator is used

(b) When the clock (a square wave) is supplied from the target system

(a) When the clock generated within the emulator is used

This method uses the clock inside the emulator by configuring the use of the subsystem clock in the user

program. For debugger settings, check the user's manual for the debugger that will be used.

(b) When the clock (a square wave) is supplied from the target system

The clock input from the target system is then used.

To input a clock from the target system, input to the clock pin (XT2) the square-wave signal with the same

voltage potential as that of the target device supply voltage (VDD).

Inputting the inverted signal to XT1 is

not necessary.

The selectable frequencies are same as those of the target device.

For debugger settings, check the user's manual for the debugger that will be used. Oscillation by a

resonator in the target system is not supported.
