A.1 Errata
A.1.1
SPI Mode Soft-reset using CTRL_REG2 (0x2B), bit 6
Description:
Following a soft-reset command, issued by setting CTRL_REG2[rst] = 1, certain device-specific parameters do not get updated
correctly from NVM, causing inaccurate data output and incorrect WHOAMI (0x0D) register content. This behavior happens only
in SPI mode. In I²C mode the device works as advertised.
Workaround:
Avoid using soft-reset in SPI mode by alternately utilizing the hardware RESET pin.
