Notes: 1) The low time on EMU0/1-IN should be at least one TCK cycle and less than 10 s. Software will set the EMU0/1-OUT

port to a high state.

2) To enable the open-collector driver and pullup resistor on EMU1 to provide rise/fall time of greater than 25 ns, the

modification shown in this figure is suggested. Rise times of more than 25 ns can cause the emulator to detect false

edges during the RUNB command or when the external counter selected from the debugger analysis menu is used.
