Bus Read Operation
To perform a bus read operation, CEx (refer to
CEx is the device-select control; when active, it enables the flash memory device. OE# is the data-
output control; when active, the addressed flash memory data is driven onto the I/O bus. For all
read states, WE# and RP# must be de-asserted. See

states.
Bus Write Operation
Writing commands to the Command User Interface enables various modes of operation, including
the reading of array data, CFI data, identifier codes, inspection and clearing of the Status Register,
and, when V
The Block Erase command requires appropriate command data and an address within the block to
be erased. The Byte/Word Program command requires the command and address of the location to
be written. Set Block Lock-Bit commands require the command and block within the device to be
locked. The Clear Block Lock-Bits command requires the command and address within the device.
The CUI does not occupy an addressable memory location. It is written when the device is enabled
and WE# is active. The address and data needed to execute a command are latched on the rising
edge of WE# or the first edge of CE0, CE1, or CE2 that disables the device (see

With CEx asserted, and OE# at a logic-high level (V

NOTE: For single-chip applications, CE2 and CE1 can be connected to V
