description
Positive power input, an external 0.1u F power decoupling capacitor is required. mon ground, shall be connected to the ground wire of the USB bus
Connected to the VCC input external power at the supply voltage of 3.3V
The external capacity is 0.1u F decoupling capacitor at 5V supply voltage
Input terminal of the crystal oscillator, required to be connected to an external crystal and oscillation capacitor.
For the built-in clock mode, XI shall be connected to GND
