LVDS bus data output control

eishishibusawa — Thu, 19 Oct 2017 01:12:12 GMT

Dear Sir

Customer want to stop(disable) and re-start(enable) the output data on LVDS bus(LVDS_TX0, LVDS_TX1, LVDS_TX2, LVDS_TX3 and LVDS_CLK).

I think that it is able to control with LDB_CTRL[chx_mode[1:0]].

Q1.

Can I dynamically change disable/enable by setting LDB_CTRL[chx_mode[1:0]]?

Q2.

When disabling the LDB Channel #0 Serializer, can I choose either LDB_CTRL[ch0_mode[1:0]] = 0b00 or LDB_CTRL[ch0_mode[1:0]] = 0b10?

Q3.

Is it enough to set LDB_CTRL[ch0_mode[1:0]] to 0b01 or 0b11 when re-enabling LDB Channel #0 Serializer?

Best Regards,

Eishi SHIBUSAWA

I confirmed by using Sabre board.

It seems to be Disable for both LDB_CTRL[ch1_mode[1:0]] = 0b00 and 0b10 settings.

It seems to be able to dynamically disable and enable.
