Capacitor values are for design guidance only.
These capacitors were tested with the resonators
listed below for basic start-up and operation. These
values were not optimized.
Different capacitor values may be required to produce
acceptable oscillator operation. The user should test
the performance of the oscillator over the expected
V

information.

When using resonators with frequencies
above 3.5 MHz, the use of HS mode rather
than XT mode is recommended. HS mode
may be used at any V
controller is rated. If HS is selected, it is
possible that the gain of the oscillator will
overdrive the resonator. Therefore, a
series resistor should be placed between
the OSC2 pin and the resonator. As a

The ECIO Oscillator mode requires an external clock
source to be connected to the OSC1 pin. There is no
oscillator start-up time required after a Power-on Reset
or after an exit from Sleep mode.
In the ECIO Oscillator mode, the OSC2 pin becomes
an additional general purpose I/O pin. The I/O pin
becomes bit 6 of PORTA (RA6). Figure 4-3 shows the
pin connections for the ECIO Oscillator mode.
