3.3V Uniform Sector

Dual and Quad Serial Flash

GD25S512MD

Program/Erase Suspend (75H) command (The Erase Suspend will set the SUS1 to 1,and the Program Suspend will set the

SUS2 to 1). The SUS1 and SUS2 bit are cleared to 0 by Program/Erase Resume (7AH) command, software reset (66H+99H)

command as well as a power-down, power-up cycle.

PE bit

The Program Error (PE) bit is a read only bit that indicates a program failure. It will also be set when the user attempts

to program a protected array sector or access the locked OTP space.

Error bits can be reset by CLEAR FLAG STATUS REGISTER command (30H).

EE bit

The Erase Error (EE) bit is a read only bit that indicates an erase failure. It will also be set when the user attempts to

erase a protected array sector or access the locked OTP space.

Error bits can be reset by CLEAR FLAG STATUS REGISTER command (30H).

ADP bit

The Address Power-up (ADP) bit is a non-volatile writable bit that determines the initial address mode when the device

is powered on or reset. This bit is only used during the power on or device reset initialization period. When ADP=0(factory

default), the device will power up into 3-Byte address mode, the Extended Address Register must be used to access memory

regions beyond 128Mb. When ADP=1, the device will power up into 4-Byte address mode directly.

ADS bit

The Address Status (ADS) bit is a read only bit that indicates the current address mode the device is operating in. The

device is in 3-Byte address mode when ADS=0 (default), and in 4-Byte address mode when ADS=1.

DRV1, DRV0 bits

The DRV1&DRV0 bits are used to determine the output driver strength for the Read operations.
