Two of the primary Oscillator modes use an external
clock. These modes are EC and EC with IO.
In the EC mode (Figure 18-4), the OSC1 pin can be
driven by CMOS drivers. In this mode, the OSC1 pin is
high-impedance and the OSC2 pin is the clock output
(F
synchronization purposes.

In the EC with IO mode (Figure 18-5), the OSC1 pin
can be driven by CMOS drivers. In this mode, the
OSC1 pin is high-impedance and the OSC2 pin
becomes a general purpose I/O pin. The feedback
device between OSC1 and OSC2 is turned off to save
current.
