S32k flexIO shifter match store mode

[yuegao1996]

Hi,

      in match store mode,  the manual says higher 16 bits are used to set the data to be matched and the lower to mask the results.  Since the shifter is 32bit, so how does it be compared to SHIFTBUF[31:16], and how data is received when a match occurs?

      You can refer to the process in the figure below.

Hi Jim, 

does this mean that as far as the higher 16 bits matched, then the whole 32 bit data in the shifter will be loaded to the shiftbuf?

many thanks,

Yuri

       yes, I think it should be like this.

      The step"n+2"  says: "when match occur store shifter data into the buffer, and set some flag bit".
