为什么m24sr64应该在令牌释放序列期间阻止SCL线？

你好
我使用NFC内存m24sr64和专用源代码（'STM32CubeExpansion_NFC1_V1.6.0'）。
我有一个使用i2c令牌释放序列的问题，应该关闭i2c会话。
事实上，我们的micro发送开始条件和从属地址，但是，然后，ms24sr将SCL线路阻塞到低电平28ms，然后再释放它。
然后发生停止条件。
因此，在i2c令牌释放序列期间，我们的micro发送8个时钟周期用于开始和从属地址，第9个出现在28ms之后。
因此，与m24sr64数据表上的序列相比，令牌释放序列似乎不正确。
您是否知道为什么m24sr64应该在令牌释放序列期间阻止SCL线，尽管我们发送了正确的地址？
谢谢 ！

hello
i use the nfc memory m24sr64 with the dedicated source code ('STM32CubeExpansion_NFC1_V1.6.0').
I have an issue using the i2c token release sequence, supposed to close the i2c session.
In fact, our micro sends the start condition and the slave adress, but then, the ms24sr blocks the SCL line to low level for 28ms before releasing it.
Then the stop condition occurs.
So, during the i2c token release sequence, our micro sends 8 clock period for the start and the slave adress, and the 9th appears 28ms later.
So, the token release sequence seems not being correct, compared to the sequence on the m24sr64 datasheet.
Do you have an idea why the m24sr64 should block the SCL line during the token release sequence, although we send its correct adress ?
thank you !
