CONFIGURATION OPERATIONS
Configuration commands generally require the configu-
ration password. The exception is that programming a
new read/write password requires the old read/write
password and not the configuration password. In most
cases these operations will be performed by the equip-
ment manufacturer or end distributor of the equipment or
card.
Configuration Read/Write
Configuration read/write allows access to all of the non-
volatile memory arrays regardless of the contents of the
configuration registers. Access includes sector writes,
random and sequential reads using the same format as
normal reads and writes.
In general, the configuration read/write operation enables
access to any memory location that may otherwise be
limited. The configuration password, in this sense, is like
a master key that can override the limits caused by the
control partitioning of the arrays.
