3.2 Clock Settings
3.2.1 Overview of clock settings
(1) Clock that is already mounted on emulation board
(2) Clock that is mounted by user
(3) External clock
or “(2) Clock that is mounted by user”. For an internal clock, the target device is connected to a resonator and the
target device’s internal oscillator is used. An example of the external circuit is shown in part (a) of Figure 3-2. During
emulation, the resonator 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-78K4-NS.
oscillator is not used. An example of the external circuit is shown in part (b) of Figure 3-2.
The main system clock to be used during debugging can be selected from (1) to (3) below.
If the target system includes an internal clock, select either “(1) Clock that is already mounted on emulation board”
If the target system includes an external clock, select “(3) External clock”.
For an external clock, a clock signal is supplied from outside of the target device and the target device’s internal
