The STAT register is saved in the filterSTAT_tag location. The output of the fil- tering operation in the example is located in AC0 (lower word) and AC1 (high word). This 32 bit result is stored in the SampleOut RAM location. R0 should be pointing to the oldest sample. The oldest sample, x[k±3], is overwritten by the next sample to be filtered, x[k+1]. R0 is saved in the startOfBuff pointer for the next FIR/COR instruction

Notice that R0 points backwards by one location from its starting point each time an FIR/COR instruction is executed. In the above figure, R0 would end up at successive locations in a clockwise manner.
