Notes:
1. Vcc = 2.7 V to 4.0 V, single-chip mode, output pins are open, and other pins are connected to Vss.
2. When the XIN input is a square wave.
3. Vcc = 3.0 V
4. Set the system clock to 10 MHz or 4 MHz with the PHISEL register.

(Topr = -20 °C to 85 °C (N version)/-40 °C to 85 °C (D version), unless otherwise
specified)
