● Method to cancel each command
○ READ, RDSR
? Method to cancel : cancel by CSB = “H”.

Cancel available in all areas of read mode
Figure 37. READ cancel valid timing
○ WRITE 、 PAGE WRITE
a ： Ope code or address input area
Cancel available in all
areas of rdsr mode
Figure 38. RDSR cancel valid timing
Cancellation is available by CSB=”H”.
b ： Data input area (D7 to D1 input area)
Cancellation is available by CSB=”H”.
Ope code

b
tE/W
d
c ： Data input area (D0 area)
In this area, cancellation is not available.
When CSB is set HIGH, write starts.
By continuing to input SCK clock without rising CSB,
SCK
c
the command will be page write command.

D0
In page write mode, there is write enable area
at every 8 clocks.
b
c
d ： tE/W area
Figure 39. WRITE cancel valid timing
In the area c, by rising CSB, write starts.
While writting, by any input, cancellation cannot be made.
Note1) If Vcc is made OFF during write execution, designated address data is not guaranteed, therefore write it once
again.
Note2) If CSB is rised at the same timing as that of the SCK rise, write execution / cancel becomes unstable, therefore, it is
recommended to rise in SCK = “L” area. As for SCK rise, assure timing of tCSS / tCSH or more.
○ WRSR
a ： From ope code to 15-th clock rise

Cancellation is available by CSB=”H”.
b ： From 15-th clock rise to 16-th clock rise (write enable area)

c ： After 16-th clock rise.
Cancellation is available by CSB=”H”.

However, if write starts (CSB is rised)
in the area b, cancellation cannot be made by any means.
And, by inputting on SCK clock, cancellation cannot be made.

Figure 40. WRSR cancel valid timing
Note1) If Vcc is made OFF during write execution, designated address data is not guaranteed, therefore write it once
again
Note2) If CSB is rised at the same timing as that of the SCK rise, write execution / cancel becomes unstable, therefore, it
is recommended to rise in SCK = “L” area. As for SCK rise, assure timing of tCSS / tCSH or more.
