There are three power control modes. All modes other than wait mode and stop mode are referred to as standard
operating mode.
1. For N, D version only.
Standard operating mode is further separated into four modes.
In standard operating mode, the CPU clock and the peripheral function clock are supplied to operate the CPU
and the peripheral function clocks. Power consumption control is enabled by controlling the CPU clock
frequency. The higher the CPU clock frequency, the more processing power increases. The lower the CPU
clock frequency, the more power consumption decreases. When unnecessary oscillator circuits stop, power
consumption is further reduced.
Before the clock sources for the CPU clock can be switched over, the new clock source needs to be oscillating
and stable. If the new clock source is the XIN clock or XCIN clock, allow sufficient wait time in a program
until oscillation is stabilized before exiting.
