CPU frequency instructions
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
