  • Page 18 (2) Clock that is mounted by user The user can mount any clock supported by the set specifications on the IE-780862-NS-EM1. This feature is effective when debugging at a different frequency than the clock already mounted. Remove the crystal oscillator (UMCLK) that is already mounted on the emulation board, and mount the parts board on which the resonator to be used is mounted or mount the oscillator to be used.
