RC Oscillator Option
This configuration is intended to be the lowest cost option in applications where oscillator accuracy
is not important. An internal constant current source and a capacitor have been integrated on-chip,
connected between the OSC2 pin and VSS. Thus by either connecting a resistor to VDD from
OSC2 or by putting a wire strap between OSC1 and OSC2 self-oscillations at the frequency as
shown in Figure 2-2 and Figure 2-3 can be induced.
