4-MHz Oscillator
32-kHz Oscillator
Figure 19-4. RC-oscillator 2
The microcontroller block 4-MHz oscillator options need a crystal or ceramic resonator con-
nected to the OSC1 and OSC2 pins to establish oscillation. All the necessary oscillator circuitry
is integrated, except the actual crystal, resonator, C3 and C4.
Figure 19-5. 4-MHz Crystal Oscillator
Figure 19-6. Ceramic Resonator
Some applications require long-term time keeping or low resolution timing. In this case, an
on-chip, low power 32-kHz crystal oscillator can be used to generate both the SUBCL and the
SYSCL. In this mode, power consumption is greatly reduced. The 32-kHz crystal oscillator can
not be stopped while the power-down mode is in operation.
