2.3 EVM Jumper Description
The EVM has 28 user-configured jumpers on the board to allow maximum
flexibility in design and applications for TLV320IC10/11 EVM owners. Table
2–5 describes the 28 jumpers and lists the manufacturer’s default position for
each jumper. Also, there are footprints on the board for an additional 18
jumpers associated with the 6 unpopulated AIC10/11 devices, U3 to U8. Refer
to Figure 2–1, or the top layer printed-circuit board in Chapter 6,
PC Board and
Bill of Materials, for the location of all jumpers.
