Partial Write Cycle Description
The following table lists the Partial Write Cycle Description for CY7C1356C.
Document Number: 38-05538 Rev. *L
Read
Write – no bytes written
Write byte a − (DQ
Write byte b – (DQ
Write both bytes
Notes
10. X = “Don't Care”, H = Logic HIGH, L = Logic LOW, CE stands for all chip enables active. BWx = L signifies at least one bytewrite select is active, BWx = valid signifies
11. Write is defined by WE and BWX. See Write Cycle Description table for details.
12. When a write cycle is detected, all I/Os are tri-stated, even during byte writes.
13. Table only lists a partial listing of the byte write combinations. Any combination of BW
that the desired byte write selects are asserted, see Write Cycle Description table for details.
