Control Register
The control register provides the user a mechanism for
changing the watchdog timer settings. Watchdog timer bits
are nonvolatile and do not change when power is removed.
The control register is accessed with a special preamble in the
slave byte (1011) and is located at address 1FFh. It can only be
modified by performing a control register write operation. Only
one data byte is allowed for each register write operation. Prior
and WD0. The X4003/X4005 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 serial read operation. Only one byte is read by
each register read operation. The X4003/X4005 resets itself
after the first byte is read. The master should supply a stop
condition to be consistent with the bus protocol, but a stop is
not required to end this operation.
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 Register" on

The user must issue a stop after sending the control byte to
the register to initiate the nonvolatile cycle that stores WD1

RWEL: Register Write Enable Latch (Volatile)
The RWEL bit must be set to “1” prior to a write to the control
register.
