Bus Operations
The B3 flash memory device performs read, program, and erase in-system operations through the
local CPU or microcontroller. All bus cycles to or from the flash memory conform to standard
microcontroller bus cycles. Four control pins dictate the data flow in and out of the flash memory
device:

Read
The B3 flash memory device provides four read modes:
These modes are accessible independently of the V
command to the CUI to enter the corresponding mode. Upon initial device power-up or after exit
from reset, the flash memory device automatically defaults to read-array mode.
CE# and OE# must be driven active to obtain data at the outputs.
For all read modes, WE# and RP# must be at V
