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 program-
ming 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
one data byte is allowed for each register write opera-
tion. 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 pro-
tocol, but a stop is not required to end this operation.
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.
