2.3 Clock
Settings
The following four types of clock settings are available.
Each clock setting is listed below.
Clock Used
Clock Supply
Debugger Setting
(in Configuration Dialog)
(a) When the clock generated within the emulator is used
System
(b) When the clock is supplied from the target system
External
(1) High-speed system clock
Note 1
(X1 oscillator or External
input)
(c) When the oscillator (OSC1) mounted onto the emulator
is used
Clock Socket
(2) Internal high-speed
oscillation clock
Uses the clock internally generated from the emulator
–
(a) When the clock generated within the emulator is used
System
(3) Subsystem clock
Note 2
(XT1 oscillator)
(b) When the clock is supplied from the target system
External
Notes
1.
First, select “System” in the debugger settings (refer to (a) When the clock generated within the emulator is
used, in (1) High-speed system clock).
If there is no clock that can be selected, follow the descriptions below.
• If the target system clock can supply a square wave for the emulator:
Select “External” in the debugger settings (refer to (b) When the clock is supplied from the target system,
in (1) High-speed system clock).
• If the target system clock cannot supply a square wave for the emulator:
Mount onto the emulator the oscillator of the clock to be used and select “Clock Socket” in the debugger
settings (refer to (c) When the oscillator (OSC1) mounted onto the emulator is used, in (1) High-speed
system clock).
2.
First, select “System” in the debugger settings (refer to (a) When the clock generated within the emulator is
used, in (3) Subsystem clock).
If there is no clock that can be selected, it can be supplied from the target system clock. A square wave,
however, must be supplied (refer to (b) When the clock is supplied from the target system, in (3) Subsystem
clock).
Oscillation with the resonator on the target system is not supported. Therefore, the in-circuit emulator cannot emulate
the oscillation operation of the clock on the target system.
