Byte-Wide Write Enable
R
The byte-wide write enable feature of the block RAM gives the capability to write eight bit
(one byte) portions of incoming data. There are four independent byte-write enable inputs.
Each byte-write enable is associated with one byte of input data and one parity bit. All four
byte-write enable inputs must be driven in all data width configurations. This feature is
useful when using block RAM to interface with the PPC405. Byte-write enable is not
available in the Multi-rate FIFO. Byte-write enable is further described in the
RAMB16 Primitive Design Considerations”
enable logic.
When configured for a 36-bit or 18-bit wide data path, any port can restrict writing to
specified byte locations within the data word. If configured in READ_FIRST mode, the DO
bus shows the previous content of the whole addressed word. In WRITE_FIRST mode,
with identical Read and Write port widths, DO shows only the enabled newly written
byte(s). The other byte values must be ignored. In WRITE_FIRST mode with different
widths for Read and Write ports, all data on DO must be ignored.
