DS90UB933-Q1: Is there RX_LOCK_MODE?

Hello Oguri,

There is RX_LOCK_DETECT in reg 0x0C[4], and LINK_DETECT in reg 0x0C[0], in the UB933.

Hi Hamzeh,

Thank you for the feedback. But no, that is not the function I meant.

What I want is:

    The function to enable back-channel communication without the forward channel signal from Ser.

This is the function of RX_LOCK_MODE in display Des such as DS90UB948-Q1.

Thank you.

Oguri,

BC is always enabled by default. you do not need any reg to enable it.

But the exact register RX_LOCK_MODE is not avalable.

Hi Hamzeh,

In a customer's actual experiment, the back-channel from Des is not available when the forward channel signal from Ser is stopped. Without a command like RX_LOCK_MODE, it seems register access from Des to Ser is not possible when Ser is not sending forward channel data.

Do you know any way to access Ser registers from Des without the forward channel signal from Ser?

Thank you.
