ABSTRACT:
In an in-circuit emulator system, an in-circuit emulator debugger operated on a personal computer requests operation clock frequency, and transmits data for clock frequency designated by a user to an in-circuit emulator. The in-circuit emulator stores the received clock frequency data in a frequency data register. A PLL synthesizer oscillates with frequency based on the clock frequency data stored in the frequency data register to generate a clock.
