SPI Jumper Block
Logic Signal Analyzer Header (P6)
Signal
SPI-EN
Pin
1
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 33 and "GPIO
Switch Bank 1 (SW1) and 2 (SW2)" on page 34.) If SPI is on, SPI signals are routed to the
SPI connector (P11).
The following figures demonstrate how to set the SPI jumper block

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.
