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.

Cancel by CS=“L”
b ： 13 clock rise and after
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.
Note 1) If Vcc is made OFF in this area, designated address data is
not guaranteed, therefore write once again.
c ： 14 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 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.
Fig.68 ERASE, ERAL cancel available timing
2) At standby
○ Standby current
When CS is “L”, SK input is “L”, DI input is “H”, and even with middle electric potential, current does not increase.
○ Timing
As shown in Fig.69, when SK at standby is “H”, if CS is started, DI status may be read at the rise edge.
At standby and at power ON/OFF, when to start CS, set SK input or DI input to “L” status. (Refer to Fig.70)
CS=SK=DI=”H”
Wrong recognition as a start bit
If CS is started when SK=”L” or DI=”L”, a start
bit is recognized correctly.
