怎么从SPWF01Sx迁移到SPWF04Sx

你好，
我们正在尝试将电路板从SPWF01SC迁移到SPWF04SC。 SPWF04的两个附加功能是LSE和HSE外部时钟引脚。它们的数据表中没有显示SPWF04的框图，所以它默认使用STM32F429的内部RC振荡器，还是需要根据X-NUCLEO-IDW04A1评估板向我们的电路板添加振荡器？
谢谢，
史蒂夫

Hello,
We're trying to migrate a board from the SPWF01SC to the SPWF04SC. Two of the additions to the SPWF04 are the LSE and HSE external clock pins. They're not displayed on the block diagram for the SPWF04 in its datasheet so does it use the STM32F429's internal RC oscillator by default or do we need to add oscillators to our board as per the X-NUCLEO-IDW04A1 evaluation board?
Thanks,
Steve
