Revision D
The W25Q128FV is also backward compatible to Winbond’s previous generations of serial flash
memories, in which the Status Register-1&2 can be written using a single “Write Status Register-1 (01h)”
command. To complete the Write Status Register-1&2 instruction, the /CS pin must be driven high after
the sixteenth bit of data that is clocked in as shown in Figure 9c & 9d. If /CS is driven high after the eighth
clock, the Write Status Register-1 (01h) instruction will only program the Status Register-1, the Status
Register-2 will not be affected (Previous generations will clear CMP and QE bits).
