4.2 Main System Clock Setting
4.2.1 Using the clock mounted on the break board
As a factory-set condition for shipment, a component block wired as shown in Fig. 4-5 is mounted to the X1 USRCLK
socket on the IE-78044-R-EM. If the wiring of this component block remains the same as the factory-set condition, no
additional hardware adjustments are required. However, if the user prepares a component block because another clock
source is to be used, or because the wired component block has been lost, then make the connections in accordance
with the procedure described below.
When starting the screen debugger (SD78K/0), select “IE” for the clock setting on the initial setting screen or
configuration panel (this selects the internal clock of the emulator).
Prerequisites
• Component block (accessory of IE-78000-R)
• Lead wires
• Soldering tools
Procedure
①
Wire and solder the component block as illustrated below.
