Hi,

The DPHY440 will work in both the pin-strap and I2C mode, what do you mean software debugging?

Thanks

David

Hello David

two more question

1. If I2C adjustment is not used, whether it can work directly after resistance configuration;

2. Adopt I2C adjustment mode, pre_ CFG1, VSADJ_ Cfg0 do you still need to configure the up and down of these two pins?

It will work directly with the resistor configuration.

2. Adopt I2C adjustment mode, pre_ CFG1, VSADJ_ Cfg0 do you still need to configure the up and down of these two pins?

The value in the registers will match the sampled state of the pins at the rising edge of RSTN. Software can change the value of this field at a later time.

Thanks

David
