Figure 2.3 Installing the Crystal Oscillator
External Clock: Follow the procedure listed below to select the external clock.
1. Check that the emulator power switch is turned off. (Check that the power LED is not lit.)
2. Connect the user system interface cable to the user system and supply a clock signal through the EXTAL pin
from the user system.
3. Turn on the user system power and then the emulator power. The external clock source will then be
automatically specified.
Emulator Internal Clock: Specify 5.0 MHz or 6.0 MHz in the [Configuration] dialog box.
Reference:
When the emulator system program is initiated, the emulator automatically selects the MCU clock source
according to the following priority:
1. User system’s clock when an external clock is supplied from the user system
2. Crystal oscillator, if one is mounted on the emulator’s front-end unit
3. Emulator-internal clock
