Table 101. Minimum values of negative resistance (module)
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
capacitance between XTAL3 and XTAL4 pins is globally assumed equal to 4pF. The external
resistance between XTAL3 and XTAL4 is not necessary, since already present on the
silicon.
External clock drive XTAL1
When Direct Drive configuration is selected during reset, it is possible to drive the CPU clock
directly from the XTAL1 pin, without particular restrictions on the maximum frequency, since
the on-chip oscillator amplifier is bypassed. The speed limit is imposed by internal logic that
targets a maximum CPU frequency of 64 MHz.
In all other clock configurations (Direct Drive with Prescaler or PLL usage) the on-chip
oscillator amplifier is not bypassed, so it determines the input clock speed limit. Then an
external clock source can be used but limited in the range of frequencies defined for the
usage of crystal and resonator (refer also to
