6.13 DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit.
DQ5 produces â1â under these conditions which indicates that the program or erase cycle was not
successfully completed.
The device may output â1â on DQ5 if the system tries to program â1â to a location that was previously
programmed to â0.â Only the erase operation can change â0â back to â1.â Under this condition, the
device stops the operation, and while the timing limit has been exceeded, DQ5 produces â1.â
Under both these conditions, the system must hardware reset to return to the read mode.
