The clock generator generates the following clocks and controls the operation modes of the CPU, such as standby
• Main system clock f
• Subsystem clock f
• Internal low-speed oscillation clock f
• CPU/peripheral hardware clock f
The CPU starts operation when the internal high-speed oscillator starts outputting after a reset release in the
When the power supply voltage is turned on, the clock generator operation is shown in Figure 7-16 and Figure 7-17.
• High-speed system clock f
• Internal high-speed oscillation clock f
• 20 MHz internal high-speed oscillation clock f
