(2) When using 2-pin type oscillator
When using a 2-pin type oscillator, follow the procedure below (see (1) to (8) in Figure 3).
For the capacitor capacity and the resistance value, contact the capacitor distributor.
(1) Install an oscillator at the XTAL1.
(2) Install a capacitor at the C2.
(3) Install a capacitor at the C3b.
(4) Install a resistor at the Rd.
(5) Install a resistor at the Rf.
(6) Connect the XIN pin.
(7) Connect the XOUT pin.
(8) Connect the GND of the oscillator.
