56F827 Technical Data
V
PP
90
Input
V
PP
—This pin should be left unconnected as an open circuit for normal
functionality.
EXTAL
59
Input
ExternalCrystal Oscillator Input
—This input should be connected to
a 4MHz external crystal or ceramic resonator. For more information,
please refer to
Section 3.6
.
This pin can also be connected to an external clock source. For more
information, please refer to
Section 3.6.3
.
XTAL
(CLOCKIN)
60
Output
Input
Crystal Oscillator Output
—This output connects the internal crystal
oscillator output to an external crystal or ceramic resonator. If an
external clock source over 4MHz is used, XTAL must be used as the
input and EXTAL connected to
V
SS
. For more information, please refer
to
Section 3.6.3
.
External Clock Input
—This input should be used when using an
external clock or ceramic resonator.
CLKO
57
Output
Clock Output
—This pin outputs a buffered clock signal. By
programming 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 master clock at the output of the PLL. The clock
frequency on this pin can be disabled by programming the CLKO Select
Register (CLKOSR).
