(2) Clock that is mounted by user
The user is able to mount any clock supported by the set specifications on the IE-789835-NS-EM1. This is
useful when using a different frequency from that of the pre-mounted clock.
(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.

(used)
Remark
The clock that is supplied by the oscillator on the IE-789835-NS-EM1 (encircled in the figure)
is used.
(b) For subsystem clock
Mount the resonator to be used on the parts board (X1) that is already mounted on the emulation board.
Alternatively, remove the parts board and mount an oscillator.
