(2) ACC Protect (ACC) [Hardware Protection2]

The device has also hardware protect feature by ACC pin. When ACC is VIL, all sectors are locked. Should be

at VIH for all other condition

(3) Software Command Locking(SCL) [Software Protection]

The sector lock/unlock feature allows the system to determine which sectors are protected from accidental writes.

When the device is first powered up, all sectors are locked. To unlock a sector, the system must write the sector

lock/unlock command.

Enhanced I/O (VCCQ) Control

The Enhanced I/O (VCCQ) control allows the host system to set the voltage levels that the device generates at

its data outputs and the voltages tolerated at its data inputs to the same voltage level that is asserted on the

VCCQ pin. This allows the device to operate in 1.8 V and 3 V system environments as required.

For example, a VCCQ of 2.70 V to 3.15 V allows for I/O at the 3-volt level, driving and receiving signals to and

from other 3 V devices on the same bus.
