5.2 Setting the Clock Supply Circuit
■
Installing the Oscillator
To supply a clock signal from the adapter board to the main clock (X0/X1) and subclock (X0A/X1A)
of the evaluation MCU, install an oscillator and a capacitor on the oscillator IC sockets (SC2 and
SC3) on the adapter board, respectively. Figure 5.2-1 shows how to install the oscillator and capaci-
tor.

•
For the frequency and other specifications of the oscillator, refer to the data sheet for the eval-
uation MCU.
•
For the capacitance of the capacitor, refer to the data sheet for the oscillator.
•
Prepare the oscillator and the capacitor as neither of them is bundled with this product.
