2.11.2 Using an Internal Oscillator Circuit Board
(1) Kinds of Oscillator Boards
The PC7501 comes with an oscillator circuit board OSC-3 (30MHz). And an oscillator circuit board OSC-3 (20MHz) and an
oscillator circuit bare board OSC-2 are included with this product. If you use an internal oscillator circuit board (20MHz) or
OSC-2 as a main clock, choose "Internal" in the emulator debugger after replacing oscillator circuit boards to change a clock
supplied to an MCU.
