Figure 13. EBR Synchronous Read Timing Diagram
Synchronous Write: The WE signal controls the synchronous write operation. When the WE signal is high, the
write operation begins. Once the address and data are present and the Output Enable (OE) is active, a rising clock
edge (or falling edge depending on polarity) causes the data to be stored into the EBR. Figure 14 illustrates the
synchronous write timing.

Asynchronous Read: The WE signal controls the asynchronous read operation. When the WE signal is low, the
read operation begins. Shortly after the address is present, the stored data is available on the DATA port. Figure 15
illustrates the asynchronous read timing. For more information about the EBR, refer to TN1028
