form-factor compatible interfaces include 6 analog inputs, 2 of which have a multiple
function for IIC communication.
However, the 2 IIC pins have no analog input function on the Embedded Pi board. The specific IO
mapping of the pins are as below:

3.5.3 ICSP/ SPI
Among Arduino
TM
form-factor compatible interfaces, several digital IO and ICSP pins can also be
used as SPI interface by multiplexing. Embedded Pi has full compliance with Arduino
TM
on these
pins. The specific IO mapping of the ICSP pins are as below:
