Control Register

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 Register" below.

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 user must issue a stop after sending this byte to the

and WD0. The X4643/5 will not acknowledge any data

bytes written after the first byte is entered.

The Control Register is accessed at address FFFFh. It

can only be modified by performing a byte write opera-

tion directly to the address of the register and only one

data byte is allowed for each register write operation.
