Hello,   I am using a ADSP21375 to read digital data from an ADC. I measured the frame sync to be about 1MHz but when I measure a 1kHz sine wave I get two cycles in 1000 samples. This means that my data has only a sample rate of 500kHz. It would be nice if somebody could help me with this problem.   This is my code:    #define SP_CLK_DIV 0x0004 //SPORT core clock divisor  #define SP_...
