Chip Enable: CE# low activates the devices internal circuitries for

device operation. CE# high deselects the devices and switches into

standby mode to reduce the power consumption. When a device is not

selected, data will not be accepted via the serial input pin (Sl), and the

serial output pin (SO) will remain in a high impedance state.

Write Protect/Serial Data Output: A hardware program/erase protection for all or

part of a memory array. When the WP# pin is low, memory array write-protection

depends on the setting of BP3, BP2, BP1 and BP0 bits in the Status Register.

When the WP# is high, the status register are not write-protected.
