SN65DP159: About Retimer mode

Hello David-san,

Thank you for your reply.

We want to control the output using I2C registers.

We set Page1 0x10 to F0, but the output does not stop.

When the register is read again, 0F is returned.

In normal operation, it may be overwritten automatically.

How do we stop the output?

Can we control it using X-mode?

Best regards,

Please write 0xF0 to Page 1 Register 0x10h, and then write a 1 to bit 5 of Page 1 Register 0xA4h, I verified this will turn off the output.

Thanks

David

Hello David-san,

Thank you for your reply.

We tried your suggestion and confirmed that the output stopped.

However, just writing 1 to bit 5 of Page 1 Register 0xA4h stopped the output, and Page1 0x10h changed to 0xF0.

What is bit 5 of Page 1 Register 0xA4h controlling?

We want you to tell us which blocks are stopped.

If the ReTimer block stops, it is not the control we expect.

Best regards,

Please write 0xE1 to Page 1 Register 0x10h, and then write a 1 to bit 5 of Page 1 Register 0xA4h, I believe this will enable the clock first. 

Thanks

David
