//P0_16 SCL     -- default HIGH probably pullup
//P0_15 SDO/ADR -- default HIGH probably pullup
//P0_14 SDI/SDA -- default HIGH probably pullup
//P0_13 Trigger -- default LOW
//P0_12 INT1    -- default LOW
//P0_11 INT2    -- default HIGH probably pullup
//P0_10 nCS     -- default HIGH probably pullup -- from datasheet is this pin is high I2C is enabled so this is ok 
// The  Slave  Address associated  with  the KX022 is 0011111X,
// where  the  programmable  bit,  X,  is  determined by  the  assignment  of ADDR (pin 1) to GND or IO_Vdd.  
// So in this case we have adress 0011111
