MODEL:
CONFIGURATION INPUTS ADDR1 AND
ADDR2
Configuration inputs ADDR1 and ADDR2 are used to
assign an initial SMBus address to a NDM1-12 slave
device. Unique device addresses are required in
systems where multiple SMBus devices are connected
through serial interface lines SDA (SMBus data) and SCL
(SMBus clock). Bus conflicts will occur if more than one
device responds to the same SMBus address.
If serial communication is not required, or the
factory-default SMBus address of 16 decimal (or 0x10)
is acceptable, both inputs ADDR1 and ADDR2 may be
left floating. In smaller-scale systems with up to sixteen
NDM1-12 slave devices it is sufficient to utilize ADDR1
only (while ADDR2 is shorted to CRC). In this case,
SMBus addresses 16..31 (0x10..0x1F) can be assigned
through RADDR1. In larger-scale systems both RADDR1
and RADDR2 can be used, in which case any SMBus
address in the range 16..127 (0x10..0x7F) can be
assigned to the device.

Note that a number of SMBus addresses in the address
range 0..15 are reserved for special purposes (e.g.
SMBus Alert Response, SMBus Host). SMBus addresses
in the range 0..15 should be avoided, and cannot be
assigned through ADDR1 and ADDR2 configuration
inputs.
If RADDR2 is not used (and ADDR2 is connected to
CRC), the effective SMBus address is
ADDR
If both RADDR1 and RADDR2 are used, the effective
SMBus address is

Table 1 offers a summary of assigned SMBus addresses
