Hello expert,

I have question for DS80PCI102.
Is this device support I2C clock stretch? If it is yes, Should I need to apply some configuration for using this function?

Best regards,

Hi Kazuki-san,

The DS80PCI102 will work with I2C components which utilize clock stretch to complete I2C or SMBus transactions. There is no additional configuration needed.

Hi Lee-san,

Thank you for your swift reply.

This is just confirmation, This device don't has enable/disable register for clock stretch and always enable this function. Is this correct?

Hi Kazuki-san,

Yes, the DS80PCI102 is able to handle SMBus stretched clock all the time. There is no requirement to enable this function.
