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.
illustrates a block diagram of the oscillator module.
Clock sources can be supplied from external clock
circuits. In addition, the system clock source can be
supplied from one of two internal oscillators, with a
choice of speeds selectable via software. Additional
clock features include:
• Selectable system clock source between external
• Fast start-up oscillator allows internal circuits to
The oscillator module can be configured in one of the
following Clock modes:

3.
4.
Clock Source modes are selected by the FOSC<1:0>
bits in the Configuration Word 1. The FOSC bits
determine the type of oscillator that will be used when
the device is first powered.
The EC Clock mode relies on an external logic level
signal as the device clock source.
