Please tell me a "DLL in read path" in uSDHC controller.
I have question about function, clock root and usage instructions.
I'm watchin Figure 67-20 in following document.
What is a function of the box that is between ④ and ⑤ ?
I can't understand their clock root because their some difference between Figure 67-2 and 67-20.
In my understandig, the clock that is shown in ① in Figure 67-20 is ref_clk.
Is it correct ?
Does it change their name to "ipp_card_clk_in" ?
According to the descrition of DLL, the DLL can be disabled or bypassed.
What is different between disabled and bypassed ?
Is the read path same that is shown in Figure 67-20 when user disabled or bypassed the DLL ?
