USID modification
AN4440
30/36
DocID025913 Rev 1
Change USID of HVDAC2 (SELSID to VCC) and set it to 0010
•
First frame: register 29 update: initial USID = 0111b, register 29 = 11101b, SELSID = 1,
product ID = 00000010b, parity 1 = 1, parity 2 = 1. SELSID is equal to 1 which is
different from HVDAC2 and now HVDAC1 USID is no longer 0111 but 000,
differentiating both HVDACs.

•
Second frame: register 30 update: Initial USID = 0111b, register 30 = 11110b,
manufacturer ID = 00000100b, parity 1 = 1, parity 2 = 0

•
Third frame: register 31 update: Initial USID = 0111b, register 31 = 11101b,
manufacturer ID (Short) = 0001b, New USID = 0010b, parity 1 = 1, parity 2 = 1
