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.
