It must be noted that the RWEL bit can only be set,
once the WEL bit has first been enabled (See "CR
Register Write Operation").
The RWEL bit will reset itself to the default “0” state, in
one of three cases:
NOTE: Bits labelled NV are nonvolatile (See “CONTROL AND STATUS REGISTER”).
Figure 17. CR Register Format
CONTROL AND STATUS REGISTER
The Control and Status (CR) Register provides the user
with a mechanism for changing and reading the status
of various parameters of the X4023x (See Figure 17).
The CR register is a combination of both volatile and
nonvolatile bits. The nonvolatile bits of the CR register
retain their stored values even when V CC is powered
down, then powered back up. The volatile bits how-
ever, will always power-up to a known logic state “0”
(irrespective of their value at power-down).
A detailed description of the function of each of the CR
register bits follows:
WEL: Write Enable Latch (Volatile)
The WEL bit controls the Write Enable status of the
entire X4023x device. This bit must first be enabled
—After a successful write operation to any bits of the CR
register has been completed (See Figure 18).
—When the X4023x is powered down.
—When attempting to write to a Block Lock protected
region of the EEPROM memory (See "BL1, BL0: Block
Lock protection bits - (Nonvolatile)", below).
BL1, BL0: Block Lock protection bits - (Nonvolatile)
The Block Lock protection bits (BL1 and BL0) are used
to:
—Inhibit a write operation from being performed to cer-
tain addresses of the EEPROM memory array
—Inhibit a DCP write operation (changing the “wiper
position”).
The region of EEPROM memory which is protected /
locked is determined by the combination of the BL1
and BL0 bits written to the CR register. It is possible to
lock the regions of EEPROM memory shown in the
table below:
before ANY write operation (to DCPs, EEPROM mem-

enabled, then ANY proceeding (volatile or nonvolatile)
write operation to DCPs, EEPROM array, as well as
the CR register, is aborted and no ACKNOWLEDGE is
issued after a Data Byte.

disabled, LOW (0) state. The WEL bit is enabled / set
by writing 00000010 to the CR register. Once enabled,
the WEL bit remains set to “1” until either it is reset to
“0” (by writing 00000000 to the CR register) or until the
X4023x powers down, and then up again.
Writes to the WEL bit do not cause an internal high
voltage write cycle. Therefore, the device is ready for
another operation immediately after a STOP condition
is executed in the CR Write command sequence (See
Figure 18).

If the user attempts to perform a write operation on a
protected region of EEPROM memory, the operation
is aborted without changing any data in the array.
