USB to SPI Interface Evaluation Board, Rev. 1.0
Freescale Semiconductor
3
The SO signal can be connected to pin 12 (normal), pin 13 (alternate), or pin 15 (alternate) of the DB25 connector via shorting
plugs. This again is to accommodate different Freescale Evaluation Boards that at different times have used each of these pins
for the SO SPI signal.
If the Evaluation Board is to be used as an interface to a Freescale Evaluation Board, the user can select the correct pin outs for
the SPI signals and Control and Data signals by using shorting jumper plugs or wire jumpers. Consult the specific Freescale
Evaluation Board documentation for the correct signal/pin definitions for the SPI and parallel control and data signals.
