following features:
The clock controller is a circuit that controls the clock for the overall MCU. It has the
Transition of clock operation modes is as follows:
HALT mode
Note1: About PCM mode, please refer to chapter 26 (Power Management Circuit).
(CPU stop)
By using a clock multiplication circuit (PLL), the clock controller supplies a clock of up to
200 MHz to the CPU. As a multiplied figure, x1, x6, or x8 can be dynamically selected.
The clock gear contributes to reduction of the consumption current.
Writing to registers inside the clock controller is prohibited.
