Other Parts Discussed in Thread: DS90UB901Q-Q1, DS90UB902Q-Q1

Dear sir,

We try to connect NS LVDS chips "DS90UB901Q-Q1/DS90UB902Q-Q1" to DM814x.

We found LVDS chip needs I2C "clock stretching" mode support on DM814x's I2C controller.

Could you kindly advise does DM814x I2C controller support " I2C "clock stretching" mode "?

Rex,

Can you clarify the definition of clock stretching in this context?

If I2C is set up in master mode and the slave extends the clock by pulling SCL low, then yes, this is supported.

More details of what they are trying to do, will help us answer more precisely.
