emulation board” or “(2) Clock that is mounted by user”. An internal clock connects the target device to
an oscillator and uses the target device’s internal oscillation circuit. An example of an external circuit
is shown in part (a) of Figure 3-2. During emulation, the oscillator that is mounted on the target system
is not used. Instead, it uses the clock that is mounted on the emulation board which is installed for the
IE-78K0-NS-A.
device’s internal oscillation circuit. An example of an external circuit is shown in part (b) of Figure 3-2.
3.2 Clock Settings
If the target system includes an internal clock, select either “(1) Clock that is already mounted on
If the target system includes an external clock, select “(3) External clock”.
An external clock supplies a clock signal from outside of the target device and does not use the target
3.2.1 Overview of clock settings
