Hi All,

 

I am working to interface uSD card using SSP1 controller of LPC1837 (In built SD controller is fixed for some other functionality).

 

SSP1 controller is configured in master SPI mode with CPOL & CPOH as 0. I have seen the clock is coming continuously just after initialising the SSP1 module without even starting the actual transfer of the data. This is not expected behaviour, please give your inputs If I am missing anything during configuration. 

 

Thanks.
