The NAD assignment can be done via Daisy Chain (DC), (see
assignment”) as well as via Plug ID (see
NAD assignment can be distinguished on the value of the initial NAD, which is the first
data byte D0 of the MasterReq assign NAD request. For reliability reasons the
assignment mode decision is valid only if the combination of D0 to D6 (see
true. After power-on the UJA1023 message identifiers PxReq and PxResp (see

Description
Initial NAD. This byte defines the initial NAD, refer to the
related items topics
Protocol control information.
Service identifier. As SlaveResp the RSID code will be 0xF0.
Supplier ID. Fixed code 0x0011 for Philips.
Function ID. For the UJA1023 this code is fixed as 0x0000.
Slave Node Address (NAD). NAD values are in the range 1 to
127, while 0 and 128 to 255 are reserved for other purposes.
0x08 to 0x0F (D0[0] = C1, D0[1] = C2 and
D0[2] = C3) defines Plug ID; D0[3] = 1 for Plug ID
