EBR Asynchronous Reset
EBR asynchronous reset or GSR (if used) can only be applied if all clock enables are low for a clock cycle before the
reset is applied and released a clock cycle after the reset is released, as shown in Figure 2-14. The GSR input to the
EBR is always asynchronous.
Figure 2-14. EBR Asynchronous Reset (Including GSR) Timing Diagram
If all clock enables remain enabled, the EBR asynchronous reset or GSR may only be applied and released after
the EBR read and write clock inputs are in a steady state condition for a minimum of 1/f
release must adhere to the EBR synchronous reset setup time before the next active read or write clock edge.
These instructions apply to all EBR RAM, ROM and FIFO implementations. For the EBR FIFO mode, the GSR sig-
nal is always enabled and the WE and RE signals act like the clock enable signals in Figure 2-14. The reset timing
rules apply to the RPReset input vs the RE input and the RST input vs. the WE and RE inputs. Both RST and
RPReset are always asynchronous EBR inputs.
These instructions apply to all EBR RAM, ROM and FIFO implementations.
Note that there are no reset restrictions if the EBR synchronous reset is used and the EBR GSR input is disabled
