you to re-use the same pins on the SPI interface and expansion interface.
By default,

EZ-Extender .

ELVIS Oscilloscope Configuration Switch (SW1)

The oscilloscope configuration switch (
cuit signals connect to channels A and B of the oscilloscope. The switch is
used only when the board is connected to the Educational Laboratory Vir-
tual Instrumentation Suite (ELVIS) station (see
page 1-9). Each channel must have only one signal selected at a time, as
described in Table
