    PIC18F87J90 FAMILY
    3.3
    Clock Sources and
    Oscillator Switching
    Essentially, PIC18F87J90 family devices have three
    independent clock sources:
     Primary oscillators
     Secondary oscillators
     Internal oscillator
    The primary oscillators can be thought of as the main
    device oscillators. These are any external oscillators
    connected to the OSC1 and OSC2 pins, and include
    the External Crystal and Resonator modes and the
    External Clock modes. If selected by the FOSC<2:0>
    Configuration bits, the internal oscillator block (either
    the 31 kHz INTRC or the 8 MHz INTOSC source) may
    be considered a primary oscillator. The particular mode
    is defined by the FOSC Configuration bits. The details
    of these modes are covered in Section 3.4 “External
    The secondary oscillators are external clock sources
    that are not connected to the OSC1 or OSC2 pins.
    These sources may continue to operate even after the
    controller is placed in a power-managed mode.
    PIC18F87J90 family devices offer the Timer1 oscillator
    as a secondary oscillator source. This oscillator, in all
    power-managed modes, is often the time base for
    functions such as a Real-Time Clock (RTC). The
    Timer1 oscillator is discussed in greater detail in
    In addition to being a primary clock source in some
    circumstances, the internal oscillator is available as a
    power-managed mode clock source. The INTRC
    source is also used as the clock source for several
    special features, such as the WDT and Fail-Safe Clock
    Monitor. The internal oscillator block is discussed in
    The PIC18F87J90 family includes features that allow
    the device clock source to be switched from the main
    oscillator, chosen by device configuration, to one of the
    alternate clock sources. When an alternate clock
    source is enabled, various power-managed operating
    modes are available.
