Would you even know is a router has SPI unless you look at the part
numbers of the chips on the board and see if a) They support the Serial
Peripheral Interface and b) that the appropriate pins are wired to other
chip(s) which also support SPI. Whether SPI is used should be a decision
for the hardware designer and be of no interest to the user, unless
the SPI bus is brought to a connector for an add-on board - but even
then unless the user is going to design his own add-on board this will
be of no interest to the user.
