22.1
Clock pulses can be supplied either by connecting a crystal resonator or by providing external
clock input.
22.1.1
Figure 22.2 shows a typical method of connecting a crystal resonator. An appropriate damping
resistance R
should be used.
Figure 22.3 shows the equivalent circuit of a crystal resonator. A crystal resonator having the
characteristics given in table 22.2 should be used.
When PFSEL is high, the system clock (φ) frequency should be no more than 25 MHz and a
crystal resonator with frequency identical to that of the system clock (φ) should be used. When
PFSEL is low, a crystal resonator with ¼ times the frequency of the system clock (φ) should be
used.
