The communication between the LMK61E08 I2C slave and the I2C host is faulty. The read data is all at high level, and no data can be written into it. What may be the cause?

您好,能附上I2C的时序看看吗?寄存器无法读写,那么在主机发送完起始信号,发送从机地址的时候,从机是否有响应?
可以把时序附上以便分析。
您好, 那就是write 写时序是没问题的,能写进去。
在读寄存器内容的时候,没收到ACK信号。 读的时候,7bit地址后的读写位为1.
也就是1011001+1.您看下我截取的第8个clock,对应的是不是0?
