Product data sheet
Plug ID NAD assignment:
C3. Once the assign NAD MasterReq with the initial NAD ‘Plug ID configuration’ is
received, the UJA1023 compares the values of the configuration pins C3, C2, and C1 with
the values of the data bits D0[2:0]. If the values are equal and bits D0[7:4] are logic 0 and
D0[3] is logic 1, the value of D7 is used as new NAD for the UJA1023.
Next, for example, the ‘assign frame ID’ can be used to assign specific ID numbers.
The internal pull-up resistors at pin C1 to C3 are active during the assign NAD process
only. Thus it causes no permanent current (see also
consumption especially in the low-power modes.
