2.11 Selecting Clock Supply

2.11.1 Clocks

You can choose a clock supplied to the evaluation MCU by the Emulator tab in the Init dialog box of the emulator debugger.
Table 2.2 shows the clocks and their initial settings.

2.11.2 Using an Internal Oscillator Circuit Board

(1) Kinds of Oscillator Circuit Boards
The PC7501 comes with an oscillator circuit board OSC-3 (30MHz). And an oscillator circuit board OSC-3 (16MHz) and
an oscillator circuit board OSC-2 (bare board) are included with this product.
If you use the internal oscillator circuit board OSC-3 (16MHz) 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.
