The following registers are needed to power up and configure the device. To operate the device set bit

PON = “1” first (register 0x80) after that configure the device and enable interrupts before setting

SP_EN

= “1”. Changing configuration while SP_EN = “1” may result in invalid results. Register

CONFIG (0x70) is used to set the INT_MODE (SYNS,SYND).
