OSCILLATOR MODULE
3.1
Overview
The Oscillator module has a wide variety of clock
sources and selection features that allow it to be used
in a wide range of applications while maximizing perfor-
mance and minimizing power consumption. Figure 3-1
illustrates a block diagram of the Oscillator module.
Clock sources can be configured from external
oscillators, quartz crystal resonators, ceramic resonators
and Resistor-Capacitor (RC) circuits. In addition, the
system clock source can be configured with a choice of
two selectable speeds: internal or external system clock
source.
The Oscillator module can be configured in one of eight
clock modes.
1.
EC – External clock with I/O on OSC2/CLKOUT.
2.
LP – 32 kHz Low-Power Crystal mode.
3.
XT – Medium Gain Crystal or Ceramic Resonator
Oscillator mode.
4.
HS – High Gain Crystal or Ceramic Resonator
mode.
5.
RC – External Resistor-Capacitor (RC) with
FOSC/4 output on OSC2/CLKOUT.
6.
RCIO – External Resistor-Capacitor (RC) with
I/O on OSC2/CLKOUT.
7.
INTOSC – Internal oscillator with FOSC/4 output
on OSC2 and I/O on OSC1/CLKIN.
8.
INTOSCIO – Internal oscillator with I/O on
OSC1/CLKIN and OSC2/CLKOUT.
Clock Source modes are configured by the FOSC<2:0>
bits in the Configuration Word register (CONFIG). The
Internal Oscillator module provides a selectable
system clock mode of either 4 MHz (Postscaler) or
8 MHz (INTOSC).
