PAW3212DB-TJDT
13. Software Power-Down Function
The sensor can be placed in an extremely low power state (power-down mode) by setting PD_enh bit (bit 3) in the register Configuration
(address 0x06) through SPI interface. In power-down mode, all the sensor register settings are retained and can be accessed through SPI
interface as well. To get the sensor out of the power-down mode, please just reset the PD_enh bit. To get more accurate motion reports, it is
recommended that the host controller should wait at least 3ms before reading the motion reports after resetting the PD_enh bit.
14. Software Reset Function
During power-up, the sensor does not need an external power-on reset as there is an internal circuitry that performs power-on reset function
in the sensor. However the sensor can also be reset by setting the Reset bit (bit 7) of register Configuration (address 0x06). A full chip reset
will thus be executed and all the registers will be reset to power-on default values. After the reset, all the recommended register settings
must be reloaded to ensure the sensor works properly.
