The set and reset functionality of a register or a latch can be
configured as follows:
The synchronous reset has precedence over a set, and an
asynchronous clear has precedence over a preset.
Distributed SelectRAM+ Memory
Each function generator (LUT) can implement a 16 x 1-bit
synchronous
SelectRAM+ element. SelectRAM+ elements are config-
urable within a CLB to implement the following:

Table 16: Distributed SelectRAM+ Configurations
Distributed SelectRAM+ memory modules are synchronous
(write) resources. The combinatorial read access time is
extremely fast, while the synchronous write simplifies
high-speed designs. A synchronous read can be imple-
mented with a storage element in the same slice. The dis-
tributed SelectRAM+ memory and the storage element
share the same clock input. A Write Enable (WE) input is
active High, and is driven by the SR input.

by each distributed SelectRAM+ configuration.
For single-port configurations, distributed SelectRAM+
memory has one address port for synchronous writes and
asynchronous reads.
For dual-port configurations, distributed SelectRAM+ mem-
ory has one port for synchronous writes and asynchronous
reads and another port for asynchronous reads. The func-
tion generator (LUT) has separated read address inputs
(A1, A2, A3, A4) and write address inputs (WG1/WF1,
WG2/WF2, WG3/WF3, WG4/WF4).
In single-port mode, read and write addresses share the
same address bus. In dual-port mode, one function genera-
tor (R/W port) is connected with shared read and write
addresses. The second function generator has the A inputs
(read) connected to the second read-only port address and
the W inputs (write) shared with the first read/write port
