Description |
---|---|---|---|
afi_rdata_en_full |
Input |
AFI_RATE_RATIO |
Read data enable full. Indicates that the memory controller is currently performing a read operation. This signal is held high for the entire read burst.If this signal is aligned to even clock cycles, it is possible to use 1-bit even in half-rate mode (i.e., AFI_RATE=2). |
afi_rdata |
Output |
AFI_DQ_WIDTH |
Read data from the memory device. This data is considered valid only when afi_rdata_valid is asserted by the PHY. |
afi_rdata_valid |
Output |
AFI_RATE_RATIO |
Read data valid. When asserted, this signal indicates that the afi_rdata bus is valid.If this signal is aligned to even clock cycles, it is possible to use 1-bit even in half-rate mode (i.e., AFI_RATE=2). |
