FUNCTION

Board ID, clock and signal routing

Board is populated with either the DS21Q348 or the DS21448.

Please see the factory data sheet for details.

Registers in the CPLD can be easily modified using ChipView, a host-based user-interface software with the

definition file named DS21448DK02A0_CPLD.DEF. This file is included as part of the design kit documentation

download (accessed through the DS21448’s quick view data sheet) or the included CD-ROM. The definition file for

the LIU is named DS21448.def.
