Table 72.
The given values of C
printed circuit board: the negative resistance values are calculated assuming additional 5pF
to the values in the table. The crystal shunt capacitance (C
between XTAL1 and XTAL2 pins is globally assumed equal to 10pF.
The external resistance between XTAL1 and XTAL2 is not necessary, since already present
on the silicon.
