CPU frequency instructions

[中文]

The CPU has the following clock sources：

• 26M

• DCO

• 320M

• 480M

note： The CPU frequency can reach up to 240M（obtained by 480M frequency division），the CPU1 and CPU2 main frequencies can reach a maximum of 480M。

CPU frequency switch description

• It can dynamically switch the cpu frequency according to the business , in order to achieve the optimal power consumption.

  The CPU main frequency switching is relatively complex, which is implemented internally by SDK
