16 Megabit (2 M x 8-Bit) CMOS 5.0 Volt-only, Uniform Sector Flash Memory

Advanced Micro Devices 

DQ6 status bits, just as in the standard program oper-

ation. See “Write Operation Status” for more informa-

tion.

The system may also write the autoselect command

sequence when the device is in the Erase Suspend

mode. The device allows reading autoselect codes

even at addresses within erasing sectors, since the

codes are not stored in the memory array. When the

device exits the autoselect mode, the device reverts to

the Erase Suspend mode, and is ready for another

valid operation. See “Autoselect Command Sequence”

for more information.

The system must write the Erase Resume command

(address bits are “don’t care”) to exit the erase suspend

mode and continue the sector erase operation. Further

writes of the Resume command are ignored. Another

Erase Suspend command can be written after the de-

vice has resumed erasing.
