(2) Clock that is mounted by user

The user is able to mount any clock supported by the set specifications on the IE-780338-NS-EM1.

(a) For main system clock

Remove the crystal oscillator (X1) that is already mounted on the emulation board, and mount either the

parts board on which the resonator to be used is mounted or an oscillator. This method is useful when

using a different frequency from that of the pre-mounted clock.

or

oscillator

Remark The clock that is supplied by the IE-780338-NS-EM1’s resonator or oscillator (encircled in the

figure) is used.

(b) For subsystem clock

Mount the resonator to be used on the parts board (X2) that is already mounted on the emulation board.

Alternatively, remove the parts board and mount an oscillator.
