Mark 7:
I2C interface of 6-axis motion sensor. Connection of Jumper J18, J19 and J20 is shown in figure 1-7.
If I2C interface is applied, J18 and J19 should be shorted with jumper. That is to say, connect I2C signal line
to M3_2 and M3-3. INT single line can be connected to M2_2 via J20, and can be left not connected if INT
function is not configured.
If SPI interface is applied, R1 need be removed. Connect test point AD0 and nCS to specified IO port with
SDO and nCS jump wire respectively, and then short J18 and J19 with jumper.
