Replace other chip instructions#
If you cannot work after replacement or have problems with CubeMX HAL library development, you must read the following manual first.

Enhancements#
The specific usage method can be seen description of enhanced function
Enhanced GPIO design：
Support independent pull-down control (40K), when IO is a multiplexing function, it can replace external circuit resistance.
For example：
When using SDIO module, D0-D3 and CMD can use internal pull-up resistor；
When using IIC, when the IIC rate is less than or equal to 100K, an internal pull-up resistor can be used.
USB Internal optional 1.5K pull-up resistor：
USB Internal DP optional 1.5K pull-up resistor, can replace the external circuit pull-up resistor; And can realize software re-enumeration (no need to add triode control outside PCB）。
Supports multiple CRC modes：
You can select whether the input Byte size end is flipped, whether the high and low bits of the calculation result are flipped, and the calculation result is 0xFFFFFFFF XOR, CRC16/32, CRC16 polynomial.
MCO Output PLL 2-16 Divided Output Support：
More flexible clock output configuration, in addition to the original output source, the other supports the output PLL 2-16 frequency output.
Support SM1/SM3/SM4/SM7 national secret algorithm；
Precautions#
Note
Since win7 system does not have a winusb driver, and Microsoft has stopped supporting the system as early as 2020, if you need to use DAPLINK function, please upgrade to win8 or above system, or manually install the driver yourself:Zadig driver installer
