Hi Zhao-san,

I am very sorry of my feedback too late.

The customer understood no ACK is feedback in case he access unassigned I2C register. However he wants to see it in the waveform plot. Would you mind providing the wave form plot.

Hi, Imi-san

Due to there is no unassigned I2C register in GUI, so I cannot do this test on EVM.
