74 / 338 page  PIC16F882/883/884/886/887 DS41291G-page 74 2006-2012 Microchip Technology Inc. 4.7.2 TWO-SPEED START-UP SEQUENCE 1. Wake-up from Power-on Reset or Sleep. 2. Instructions begin execution by the internal oscillator at the frequency set in the IRCF<2:0> bits of the OSCCON register. 3. OST enabled to count 1024 clock cycles. 4. OST timed out, wait for falling edge of the internal oscillator. 5. OSTS is set. 6. System clock held low until the next falling edge of new clock (LP, XT or HS mode). 7. System clock is switched to external clock source. 4.7.3 CHECKING TWO-SPEED CLOCK STATUS Checking the state of the OSTS bit of the OSCCON register will confirm if the microcontroller is running from the external clock source, as defined by the FOSC<2:0> bits in the Configuration Word Register 1 (CONFIG1), or the internal oscillator.
