Internal Oscillator With External Crystal
The internal oscillator is enabled by selecting the appropriate clock mode at reset (this is de-
vice-dependent; see Section Section 3.10) and connecting a crystal or ceramic resonator across X1 and
X2/CLKIN. The CPU clock frequency is one-half, one-fourth, or a multiple of the oscillator frequency. The
multiply ratio is determined by the bit settings in the CLKMD register.
The crystal should be in fundamental-mode operation, and parallel resonant, with an effective series
resistance of 30

maximum and power dissipation of 1 mW. The connection of the required circuit,
consisting of the crystal and two load capacitors, is shown in Figure 5-2. The load capacitors, C
1
and C
2
,
should be chosen such that the equation below is satisfied. C
L
(recommended value of 10 pF) in the
equation is the load specified for the crystal.
