JP3
When using emulator as
standalone unit
Internal clock
Note 1
Oscillator mounted (a 32.768-kHz oscillator is mounted when
shipped)
Note 3
When using emulator with
target system
Internal clock

Oscillator mounted (a 32.768-kHz oscillator is mounted when
shipped)
Note 3
Target clock
Note 2
Pins 3 and 4 of JP3 are shorted
Note 4
Notes 1.
The internal clock does not support the clock input by an oscillator.
2.
The target clock supports only an oscillator (XT2 cannot be used because it is not connected in the
emulator).
Clock input by oscillator is not supported.
3.
To use a subsystem clock frequency other than 32.768 kHz, remove the clock module on JP3 and
mount
any oscillator.
The specifications of JP3 are as follows.
4.
Prepare the short pin.
