8.0
As an extension to 8-bit device addressing (Section
7.0 “8-Bit Device Addressing”), 12-bit device
addressing allows for support of a much larger number
of devices. Devices designed to support 12-bit
addressing are fully compatible with 8-bit addressable
devices, and both can be connected onto the bus
concurrently.
FIGURE 8-1:
8.1
The lower nibble (bits A
address is the family code. This code is a 4-bit value
and specifies in which family the device resides. The
families and codes are defined by Microchip and must
be followed in order to reduce the risk of address con-
flicts. 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 8-1.
TABLE 8-1:
8.2
The low byte (bits A
device code. This code is an 8-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.

The 12-bit device addressing scheme takes advan-
tage of the ‘1111’ family code defined in Section 7.1
“Family Code”. This code functions as an enable for
12-bit addressing compatible devices and will place all
other devices into Idle mode.
