19.2
Clock pulses can be supplied by connecting a crystal resonator, or by input of an external clock
signal.
19.2.1
Circuit Configuration: A crystal resonator can be connected as in the example in figure 19.2.
Damping resistance Rd should be selected according to table 19.1 (1), and external capacitances
C
If a crystal resonator with a frequency higher than 20 MHz is connected, the external load
capacitance values in table 19.1 (2) should not exceed 10 pF. Also, in order to improve the
accuracy of the oscillation frequency, a thorough study of oscillation matching evaluation, etc.,
should be carried out when deciding the circuit constants.
