13. CLOCK GENERATOR
The clock generator produces the basic clock pulses which
provide the system clock to be supplied to the CPU and pe-
ripheral hardware. The main system clock oscillator oscil-
lates with a crystal resonator or a ceramic resonator
connected to the XI and XO pins. External clocks can be
input to the main system clock oscillator. In this case, input
a clock signal to the XI pin and open the XO pin.

13.1 Oscillation Circuit
XI and XO are the input and output, respectively, a invert-
ing amplifier which can be set for use as an on-chip oscil-
lator, as shown in Figure 13-2 .
