Master Reset The FLEx36 family devices undergo a complete reset by taking its MRST input LOW. The MRST input can switch asynchro- nously to the clocks. The MRST initializes the internal burst counters to zero, and the counter mask registers ...

Address Counter and Mask Register Operations [10] This section describes the features only apply to CY7C0850AV/CY7C0851AV/CY7C0852AV devices, but not to the CY7C0853AV device. Each port of these devices has a programmable burst address counter. The burst counter contains three registers: ...
Page 9
... When the least significant bit of the mask register is “0,” the counter increments by two. This may be used to connect the CY7C0850AV/CY7C0851AV/CY7C0852AV as a 72-bit single port SRAM in which the counter of one port counts even addresses and the counter of the other port counts odd addresses. This even-odd address scheme stores one half of the 72-bit data in even memory locations, and the other half in odd memory locations ...
