Clock output to supply an external device.
An external pull-up resistor has to be added
in accordance to the driving requirements of
the external device.
The clock output frequency is 2.7 MHz when
a crystal of 10.78 MHz is used.
This pin is connected to the reference oscil-
lator circuit.
The reference oscillator is working as a neg-
ative impedance converter. It presents a
negative resistance in series to an induc-
tance at the COSC pin.
The resonance frequency of the crystal
should be 10.78 MHz to achieve an output
frequency of 345 MHz.
