Cancellation is not available by any means. If Vcc is made OFF in this area,
designated address data is not guaranteed, therefore write once again.
And when SK clock is input continuously, cancellation is not available.

Cancellation is not available by any means. If Vcc is made OFF in this area,
designated address data is not guaranteed, therefore write once again.
c ： 30 clock rise and after
Cancel by CS=“L”
However, when write is started in b area (CS is ended), cancellation is not
available by any means.
And when SK clock is output continuously is not available.

Note 1) If Vcc is made OFF in this area, designated address data is
not guaranteed, therefore write once again.
Note 2) If CS is started at the same timing as that of the SK rise,
write execution/cancel becomes unstable, therefore, it is
recommended to fail in SK=”L” area.
As for SK rise, recommend timing of tCSS/tCSH or higher.
