includes a PLL circuit, which enables the clock frequency to be multiplied by four. The clock frequency can also be
divided before clock signals are input to the CPU or on-chip peripherals. Clock oscillation can also be stopped to save
power.
The clock generator generates the clock signals that are input to the CPU and peripherals. The clock generator
The clock generator has the following features:
