Clock Generation Circuit

The clock generation circuit contains four oscillator circuits as follows:

(1) Main clock oscillation circuit

(2) Sub clock oscillation circuit

(3) Ring oscillator (oscillation stop detect function)

(4) PLL frequency synthesizer

Table 1.9.1 lists the clock generation circuit specifications. Figure 1.9.1 shows the clock generation circuit.

Figures 1.9.2 to 1.9.6 show the clock-related registers.
