Table 4-17: Block RAM ECC Port Names and Descriptions
Notes:
1. Hamming code implemented in the block RAM ECC logic detects one of three conditions: no
WRADDR<8:0>
STATUS<1:0>
RDADDR<8:0>
detectable error, single-bit error detected and corrected on DO (but not corrected in the memory), and
double-bit error detected without correction. The result of STATUS<1:0> indicates these three
conditions.
