(1) Clock that is already mounted on emulation board

(a) For main system clock

A crystal oscillator (X1) is already mounted on the emulation board. Its frequency is 10.0 MHz.

Figure 3-5. When Using Clock That Is Already Mounted on Emulation Board (Main System Clock)

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

used.

(b) For subsystem clock

A crystal resonator (XT1) is already mounted on the emulation board. Its frequency is 32.768 kHz.
