2.3.1.1 Basic Register Configuration

  • The device must be in Config mode before you are able to set register configurations

    • Set the CONFIG_MODE bit of RESET (Address 0x0A) to 1 to put the device into Config mode

  • Choose the sampling rate based on the power consumption requirement of the system by configuring the NP_SCAN_RATE (Address 0x0D) or LP_SCAN_RATE (Address 0x0F) registers

  • Ensure that the correct sensor parameters are selected by configuring the SENSORn_CONFIG registers

    • These registers are used to set the sensor Rp range, frequency range, and cycle count

  • To operate in Raw Data Mode, set the BALG_EN bit of INTPOL (Address 0x011) to 0 to disable the Button Algorithm

  • Set the CONFIG_MODE bit of RESET (Address 0x0A) to 0 to put the device back into Normal mode
