pend mode and continue the sector erase operation.

Further writes of the Resume command are ignored.

Another Erase Suspend command can be written after

the device has resumed erasing.

Temporary Unprotect Enable/Disable

Command Sequence

The temporary unprotect command sequence is a

four-bus-cycle operation. The sequence is initiated by

writing two unlock write cycles. A third write cycle sets

up the command. The fourth and final write cycle en-

ables or disables the temporary unprotect feature. If

the temporary unprotect feature is enabled, all sectors

are temporarily unprotected. The system may program

or erase data as needed. When the system writes the

temporary unprotect disable command sequence, all

sectors return to their previous protected or unpro-

tected settings. See Table 10 for more information.

Notes:

1. See Table 10 for erase command sequence.

2. See “DQ3: Sector Erase Timer” for more information.
