CPU frequency instructions

[中文]

The CPU has the following clock sources：

  • 26M

  • DCO

  • 320M

  • 480M

note： The CPU frequency can reach up to 320M; The system cannot run up to 480M，240M can be used through frequency division.。

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

  • The maximum CPU frequency is 320M
