The pinout isas in fig 3 with the orientation vertical. Look for the pin1 marker on the evaluation board.Pin Function Pin Function1 SCLOCK 6 DGND2 DGND 7 663 SDATA/MOSI 8 DGND4 DGND 9 NC5 MISO 10 DGNDTable 3: Pin functions for SPI connector J7J8 (Timer/Strobe)The timer/strobe control signals on the ADuC812 are all brought out to a 10 way connection port justabove the prototyping.
