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 (30 MHz). And an oscillator circuit board OSC-3 (16 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 (16 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.
