(a) Uses the clock internally generated from the emulator
(b) Uses the square-wave clock from the target system
(c) Uses the clock generated from the oscillator (OSC1) mounted on the emulator
(1) High-speed system clock
(a) Uses the clock internally generated from the emulator
(b) Uses the square-wave clock from the target system
(c) Uses the clock generated from the oscillator (OSC1) mounted on the emulator
The clock settings are listed below.
Note This setting is not possible when TARGET LED is not lit.
Remarks 1. Settings other than the above are prohibited.

following specifications.
Select the “System” in the debugger and select the desired frequency from the drop-down list.
The following frequencies are selectable.
2.00, 3.00, 3.57, 4.00, 4.19, 4.91, 5.00, 6.00, 8.00, 8.38, 10.00 [MHz]
Select the “External” in the debugger. The clock input from the target system is then used.
Oscillation with the resonator on the target system is not supported. To input a clock from the target
The selectable frequencies are same as those of the target device.
Mount an oscillator in the OSC1 socket in the emulator and then select the “Clock socket” in the
The selectable frequencies are same as those of the target device.
As an oscillator
- Supply voltage: 5 V
- Output level: CMOS
Note An oscillator that uses a resonator cannot be used.
2. Selection of (a) or (b) is possible regardless of whether the oscillator is not mounted in the
OSC1socket.
