Hi all,
I am trying to develop a Datalogger for the MPC555 using sd card . I want to implement a QSPI interface for this.
I found one application note from the MMCA which suggests a design , for the hardware interface,in the following manual at page 23:
There is one more App note from Kingmax which suggests a design at
I want to know what are the usual/exact values of the (pull-up ? ) resistors and capacitors used in the interface. I read somewhere that there should be only a particular set of values of the resisitors and capactors through which data transfer is possible !!
Any ideas would be appreciated.
Thanks in advance, Amit.
