Memory ICs
(3) Canceling modes
1) Read commands
2) Write commands
Cancellation method: CS HIGH
Canceling methods
a : Canceled by setting CS HIGH. The WC pin is not involved.
b : If the WC pin goes HIGH for even a second, writing is forcibly interrupted. Cancellation occurs even if the CS pin is
c : The operation is forcibly canceled by setting the WC pin to HIGH or turning off the power supply (although we do
d : If CS is set to HIGH while the R / B signal is HIGH (following the tE / W timing), the IC is reset internally, and waits
HIGH. At this point, data has not been written to the memory, so the data in the designated address has not yet
been changed.
not recommend using this method). The data in the designated address is not guaranteed and should be written
once again.
