standalone unit
When using emulator with
target system
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.
