JTAG SWD connection
The simplest implementation of ICP is to just wire an adapter cable from a JTAG programmer such that the
pin numbers on the programmer are connected to the connections detailed.
NOTE: There is also a Production Test fixture PCB for USRIC with connections/interfacing for LTI and
programming.
