DS90UB948-Q1: how to set Internal Default Timing Configuration?

hi

We want to set DS90UB948 into Internal Timing mode so it can generate test patterns without FPD-Link III.

Like this:

I only find this file, but it does not contain DS90UB948.  http://www.ti.com/lit/an/snla132c/snla132c.pdf

In Register 0x65,  how to set bit 2?  we don't have any clock or timing source input to 948.

If set bit 2=1,  Do I need set the Internal Timing Default Values ,  as the table 10 listed in the file of snla132c.pad.

If yes,  I can not find the suitable registers to set them.

Thanks a lot!
