4) Command cancellation by start and stop condition
During a command input, it is canceled by the successive inputs of start condition and stop condition. (Fig.4)
But during ACK or data output, the device may output the SDA line LOW. In such cases, operation of start and stop
condition is impossible, so that the reset can’t work. Execute the software reset in the cases. (See Page14)
Operating the command cancel by start and stop condition during the command of Random Read or Sequential Read
or Current Read, internal address counter is not confirmed.
Therefore operation of Current Read after this in not valid. Operate a Random Read in this case.
