Clock-generating Circuit
X
The clock generating circuit contains two oscillator circuits that supply the operating clock sources to the CPU and
internal peripheral units. Figure 1.18 shows the block diagram of the clock-generating circuit. Table 1.23 lists the main
clock-generating circuits.
IN
When the oscillation drive capacity is set to low, check that oscillation is stable.
capacity setting. Use the value recommended by the maker of the oscillator.
