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 26 and "GPIO
Switch Bank 1 (SW1) and 2 (SW2)" on page 27.) If SPI is on, SPI signals are routed to the
SPI connector (P11).
The following figures demonstrate how to set the SPI jumper block
