Setting a Lower V
TRIPx
Voltage (x=1, 2)
In order to set V
TRIPx
to a lower voltage than the
present value, then V
TRIPx
must first be “reset” accord-
ing to the procedure described below. Once V
TRIPx
has been “reset”, then V
TRIPx
can be set to the desired
voltage using the procedure described in “Setting a
Higher V
TRIPx
Voltage”.
Resetting the V
TRIPx
Voltage
To reset a V
TRIPx
voltage, apply the programming volt-
age (Vp) to the WDO pin before a START condition is
set up on SDA. Next, issue on the SDA pin the Slave
Address A0h followed by the Byte Address 03h for
V
TRIP1
and 0Bh for V
TRIP2
, followed by 00h for the
Data Byte in order to reset V
TRIPx
. The STOP bit fol-
lowing a valid write operation initiates the programming
sequence. Pin WDO must then be brought LOW to
complete the operation.
After being reset, the value of V
TRIPx
becomes a nomi-
nal value of 1.7V or lesser.
Note:
This operation does not corrupt the memory
array.
CONTROL REGISTER
The Control Register provides the user a mechanism
for changing the Block Lock and Watchdog Timer set-
tings. The Block Lock and Watchdog Timer bits are
nonvolatile and do not change when power is removed.
The Control Register is accessed with a special pre-
amble in the slave byte (1011) and is located at
address 1FFh. It can only be modified by performing a
byte write operation directly to the address of the regis-
ter and only one data byte is allowed for each register
write operation. Prior to writing to the Control Register,
the WEL and RWEL bits must be set using a two step
process, with the whole sequence requiring 3 steps.
See "Writing to the Control Registers" on page 7.
The user must issue a stop, after sending this byte to
the register, to initiate the nonvolatile cycle that stores
WD1, WD0, PUP1, PUP0, BP1, and BP0. The X40010/
11/14/15 will not acknowledge any data bytes written
after the first byte is entered.
The state of the Control Register can be read at any
time by performing a random read at address 01Fh,
using the special preamble. Only one byte is read by
each register read operation. The master should sup-
ply a stop condition to be consistent with the bus proto-
col, but a stop is not required to end this operation.
RWEL: Register Write Enable Latch (Volatile)
The RWEL bit must be set to “1” prior to a write to the
Control Register.
