TIP #1 Dual Speed RC Oscillator
1. After reset I/O pin is High-Z
2. Output '1' on I/O pin
3. R1, R2 and C determine OSC frequency
4. Also works with additional capacitors
Frequency of PIC MCU in external RC oscillator
mode depends on resistance and capacitance on
OSC1 pin. Resistance is changed by the output
voltage on GP0. GP0 output '1' puts R2 in parallel
with R1 reduces OSC1 resistance and increases
OSC1 frequency. GP0 as an input increases the
OSC1 resistance by minimizing current flow
through R2, and decreases frequency and power
consumption.
Summary:
GP0 = Input: Slow speed for low current
GP0 = Output high: High speed for fast processing
