SPI Jumper Block
The SPI jumper block determines whether the SPI connector is connected or not. If SPI is
off (the default), serial and GPIO signals are routed to switch banks 1 through 4. (See
"Serial/GPIO Switch Bank 3 (SW3) and Switch Bank 4 (SW4)" on page 31 and "GPIO
Switch Bank 1 (SW1) and 2 (SW2)" on page 32.) If SPI is on, SPI signals are routed to the
SPI connector (P11).
The following figures demonstrate how to set the SPI jumper block

Logic Signal Analyzer Header (P6)
This 20-pin male vertical header (labeled P6) connects a digital signal analyzer (for
example, a logic analyzer) to the development board. It is used with the development kit
only. See the following figure and table for pin orientation and pin assignments.
