Asserting RESET# During A Burst Access
If RESET# is asserted low during a burst access, the burst access is immediately terminated and
the device defaults back to asynchronous read mode. See
Hardware Reset (RESET#)
on page 71
for more information on the RESET# function.
Configuration Register
The device contains a Configuration Register for configuring read accesses. The Configuration
Register is accessed by the Configuration Register Read and the Configuration Register Write com-
mands. The Configuration Register does not occupy any addressable memory location, but rather,
is accessed by the Configuration Register commands. The Configuration Register is readable any
time, however, writing the Configuration Register is restricted to times when the Embedded Algo-
rithm is not active. If the user attempts to write the Configuration Register while the Embedded
Algorithm is active, the write operation is ignored and the contents of the Configuration Register
remain unchanged.
The Configuration Register is a 16 bit data field which is accessed by DQ15–DQ0. During a read
operation, DQ31–DQ16 returns all zeroes.
Table 33
shows the Configuration Register. Also, Con-
figuration Register reads operate the same as Autoselect command reads. When the command is
issued, the bank address is latched along with the command. Reads operations to the bank that
was specified during the Configuration Register read command return Configuration Register con-
tents. Read operations to the other bank return flash memory data. Either bank address is
permitted when writing the Configuration Register read command.
