configuration.
Table 5-5: Distributed RAM Configuration
For single-port configurations, distributed RAM has a common address port for
synchronous writes and asynchronous reads. For dual-port configurations, distributed
RAM has one port for synchronous writes and asynchronous reads, and another port for
asynchronous reads. In simple dual-port configuration, there is no data out (read port)
from the write port. For quad-port configurations, distributed RAM has one port for
synchronous writes and asynchronous reads, and three additional ports for asynchronous
reads.
In single-port mode, read and write addresses share the same address bus. In dual-port
mode, one function generator is connected with the shared read and write port address.
The second function generator has the A inputs connected to a second read-only port
address and the WA inputs shared with the first read/write port address.

driven High by the software to keep O5 and O6 independent.
Notes:
