■ How to oscillator mounting on a MCU board
Mount the crystal or ceramic oscillator into the crystal oscillator mounting sockets (for the main
clock and sub clock) on the MCU board.
The MCU board has one crystal oscillator mounting socket for the main clock and the other for the
sub clock. To distinguish them from each other, the board has the “MAIN CLOCK” and “SUB
CLOCK” labels printed near the main clock socket and sub clock socket, respectively. Mount the
crystal or ceramic oscillator along with a capacitor on the MCU board (see “Figure 7”).

• For information on the crystal oscillator such as its frequency, refer to the datasheet
for the evaluation MCU.
• For the capacitance of the capacitor, refer to the datasheet for the crystal oscillator, etc.
• Neither the crystal oscillator nor the capacitor is bundled with this product.
