2.10.2 Selecting Clock Supply
With this product, a clock supply can be set in Init dialog box of Emulator tab of the emulator debugger. Table 2.4 lists the
factory-settings of each clock supply.

IMPORTANT
Notes on Changing the Clock Supply:
 The clock supply can be set by the Init dialog box when starting up the emulator debugger or inputting CLK
command on the script window.
 For XCIN-XCOUT, it is necessary to set switches in the emulator. For details, refer to "2.10.1 Setting Switches of
Emulation Probe" (page 38).
(1) Using an Internal Oscillator Circuit Board
1) Kinds of Oscillator Circuit Boards
The PC7501 comes with an oscillator circuit board OSC-3 (30 MHz). And an oscillator circuit board OSC-3 (32 MHz)
and an oscillator circuit board OSC-2 (bare board) are included with this product. If you use the internal oscillator
circuit board OSC-3 (32 MHz) or OSC-2 of the PC7501 as a main clock, choose "Internal" in the emulator debugger
after replacing oscillator circuit boards to change a clock supplied to an MCU.
