Part Number: LMK04832

Hello,

I see that the CLKSEL0 & CLKSEL1 pins can be programmed to be used for readback outputs.

I do not fully understand what is possible to be read back...

1. If used for readback, do they replace the SDIO pin for readback function?

2.Is there any information that can be read back from teh CLKSEL0 & CLKSEL1 pins that cannot be read from the SDIO pin?

Regards,

Itai

Hello Itai

If you use 4-wire interface then CLKSEL0/CLKSEL1 can be programmed to be used as SDO (readback). In this case you need two data pins, one for input and one for readback.
