No Known Errata
The maximum frequency for the Full Swing Crystal Oscillator is 8MHz. For Crystal frequen-
cies > 8MHz the Full Swing Crystal Oscillator is not guaranteed to operate correctly.
Problem fix/Workaround
If a Crystal with frequency > 8MHz is used, the Low Power Crystal Oscillator option should
be used instead. See table 8-1 for an overview of the Device Clocking Options. Note that the
Low Power Crystal Oscillator will not provide full rail-to-rail swing on the XTAL2 pin. If sys-
tem clock output is needed to drive other clock inputs while running from the Low Power
Crystal Oscillator, the system clock can be output on PORTC7 by programming the CKOUT
fuse.
