The external Resistor-Capacitor (RC) modes support the use of an external RC circuit. This allows the designer maximum flexibility in frequency choice while keeping costs to a minimum when clock accuracy is not required. There are two modes: RC and RCIO.

In RC mode, the RC circuit connects to OSC1. OSC2/CLKOUT outputs the RC oscillator frequency divided by 4. This signal may be used to provide a clock for external circuitry, synchronization, calibration, test or other application requirements. Figure 4-5 shows the external RC mode connections after  recover pic16f873 IC.

The INTOSC and INTOSCIO modes configure the internal oscillators as the system clock source when (SCS) bit of the OSCCON register. user-adjusted via software using the OSCTUNE register (Register 4-2).

2. The LFINTOSC (Low-Frequency Internal Oscillator) is uncalibrated and operates at 31 kHz. The system clock speed can be selected via software.

INTERNAL CLOCK MODEL

The Oscillator module has two independent, internal oscillators that can be configured or selected as the system clock source.

1. The HFINTOSC (High-Frequency Internal Oscillator) is factory calibrated and operates at 8 MHz. The frequency of the HFINTOSC can be user-adjusted via software using the OSCTUNE register (Register 4-2) for the purpose of recover microcontroller tms320f2812pgfa firmware.

2. The LFINTOSC (Low-Frequency Internal Oscillator) is uncalibrated and operates at 31 kHz. The system clock speed can be selected via software using the Internal Oscillator Frequency Select bits IRCF<2:0> of the OSCCON register. an>

The INTOSC and INTOSCIO modes configure the internal oscillators as the system clock source when bit of the OSCCON register. See Section 4.6  user-adjusted via software using the OSCTUNE register (Register 4-2).
