Legend
A[3:0] = Address bits. These bits are the slave address. For
programmable devices these bits are all set to zero. For pre-
programmed devices these bits contain the pre-programmed
address and must match the PA[3:0] bits.
G[1:0] = Group bits. These bits are the group number for the slave.
These bits are not used by this device and should be set to “0”.
PA[3:0] = Program Address bits. These bits are the address that is
to be stored into the slave’s address register.
Legend
A[3:0] = Address bits.The slave address.
BF = Bus Fault. BUSIN short to battery detected.
BS = Controls closing of the Bus Switch (1=close).
G[1:0] = Group bits. Not used on this part, will be set to “0”. The
group number programmed into the slave.

NV
A3
NV = Nonvolatile Memory Write. The value of the NV bit in the slave.
PA[3:0] = Bus Address to set the device to.
X[3:0] = Cyclic Redundancy Check (CRC). The CRC as calculated by the
slave.
BS
NV = Nonvolatile Memory Write. When set to a one, this bit allows a
subsequent NVM command to store a nonvolatile address. When set to a
zero, NVM programming is disallowed. Once a permanent address has
been stored in the device, setting the NV bit to a one has no effect.
X[3:0] = Cyclic Redundancy Check (CRC). The CRC as calculated by the
master.
