2.0
2.1
Devices in the PIC18F46J11 family incorporate a
different oscillator and microcontroller clock system
than general purpose PIC18F devices.
The PIC18F46J11 family has additional prescalers and
postscalers, which have been added to accommodate
a wide range of oscillator frequencies. Figure 2-1
provides an overview of the oscillator structure.
Other oscillator features used in PIC18 enhanced
microcontrollers, such as the internal oscillator block
and clock switching, remain the same. They are
discussed later in this chapter.
2.1.1
The operation of the oscillator in PIC18F46J11 family
devices is controlled through three Configuration regis-
ters and two control registers. Configuration registers,
CONFIG1L, CONFIG1H and CONFIG2L, select the
oscillator mode, PLL prescaler and CPU divider
options. As Configuration bits, these are set when the
device is programmed and left in that configuration until
the device is reprogrammed.
The OSCCON register (Register 2-2) selects the Active
Clock mode; it is primarily used in controlling clock
switching in power-managed modes. Its use is
discussed in Section 2.3.1 “Oscillator Control
Register”.
The OSCTUNE register (Register 2-1) is used to trim the
INTOSC frequency source and select the low-frequency
clock source that drives several special features. The
OSCTUNE register is also used to activate or disable the
Phase Locked Loop (PLL). Its use is described in
Section 2.2.5.1 “OSCTUNE Register”.
2.2
PIC18F46J11 family devices can be operated in eight
distinct oscillator modes. Users can program the
FOSC<2:0> Configuration bits to select one of the
modes listed in Table 2-1. For oscillator modes which
produce a clock output (CLKO) on pin RA6, the output
frequency will be one fourth of the peripheral clock
frequency. The clock output stops when in Sleep mode,
but will continue during Idle mode (see Figure 2-1).
