7.0
In order to differentiate individual slave devices on the
bus, a device address byte is sent by the master
device following the start header. This is an 8-bit value
used to select a specific device attached to the bus.
The device address byte consists of a 4-bit family code
and a 4-bit device code. The device code may be
either fixed or programmable in order to provide the
ability to cascade multiple devices with identical family
codes on the same bus.

the family code. This code is a 4-bit value and speci-
fies in which family the device resides. The families
and codes are defined by Microchip and must be fol-
lowed in order to reduce the risk of address conflicts.
To obtain the proper code for a specific device, please
contact Microchip.
Certain codes have been reserved for special
functions and are listed in Table 7-1.

The lower nibble (bits A
the device code. This code is a 4-bit value and is used
to differentiate between multiple devices on the bus
within the same family. The device code is defined at
the device level and can be either fixed or customiz-
able. Such customizable bits can be implemented in
any manner, including via external input pins or
software configuration.
It is strongly recommended that as many customizable
device code bits as possible be included in order to
help avoid address conflicts.
