pull up resistor
Dear All,
I have doubt about pull-up resistor selection in SD Memory Card Interface with System (Normally processor). In SD Card Product manual (Sandisk) they given pull-up resistor range is 10K - 100K. How I can identify exact the pull-up resistor value for my requirement.
Just I select the 50K ohm for CMD, D0-3. It is correct or otherwise I need to take any precaution when selecting pull-up resistor.
One more doubt also, the SD Memory Card have any internal pull-up resistor within that
