如何将XTAL频率信息存储到非易失性存储器中

你好，
CYW92070XV3EVAL评估板硬件用户指南称，CYW20706或CYW20707上的PIN BTXXTALYSTRAPGL0和BTXXTALYSTRAPGL1可以用来选择XTAL频率，并且它还表示在BTXXTALYSTRAP0SP0和BTXXTALYSTRAPHL1上的1的值使得CYW20706／07能够读取来自非易失性存储器。
问题：
你能帮助我理解如何将XTAL频率信息存储到非易失性存储器中吗？XTAL信息何时读取并应用？XTAL FRQ是如何使用的？
这将是非常有用的，如果你可以直接在WSDE SDK 5的地方，这已经完成了。
谢谢您，
普拉文库马

  Hi,

CYW92070xV3_EVAL evaluation board hardware user guide says that pin BT_XTAL_STRAP_0 and BT_XTAL_STRAP_1 on CYW20706 or CYW20707 can be used to select XTAL frequency and it also says that the value of 1 on both BT_XTAL_STRAP_0 and BT_XTAL_STRAP_1 makes the CYW20706/07 to read the frequency from Non volatile memory.


Question :

Can you help me understand how to store XTAL frequency information into Non volatile memory ? When is this XTAL info read and applied ? How the XTAL freq used ?

It would be very helpful if you can direct to place in WICED SDK 5.0 where this is already being done.


Thank you,
