EXTAL
Input
External Crystal Oscillator Input—This input should be connected to
an 8MHz external crystal or ceramic resonator. For more information,
please refer to Section 3.5.

XTAL
Input/
Output
Chip-driven
Crystal Oscillator Output—This output should be connected to an
8MHz external crystal or ceramic resonator. For more information,
please refer to Section 3.5.
This pin can also be connected to an external clock source. For more
information, please refer to Section 3.5.3.
1
CLKO
Output
Chip-driven
Clock Output—This pin outputs a buffered clock signal. By
programming the CLKOSEL[4:0] bits in the CLKO Select Register
(CLKOSR), the user can select between outputting a version of the
signal applied to XTAL and a version of the device’s master clock at the
output of the PLL. The clock frequency on this pin can also be disabled
by programming the CLKOSEL[4:0] bits in CLKOSR.
