1. Register contents are preserved when transitioning from Active to Standby mode.
2. Register contents are reset when transitioning from Standby to Active mode.
3. Register contents can be modified anytime in Standby or Active mode. A write to this register will cause a reset of the corresponding internal
system debounce counter.
4. Modification of this register’s contents can only occur when device is in Standby mode, except the FS[1:0] bit fields in CTRL_REG1 register.
NOTE
The auto-increment addressing is only enabled when registers are read using burst-read mode when the device is configured for
I²C or SPI. The auto-increment address is automatically reset to 0x00 in I²C mode when a stop condition is detected. In SPI mode
there is no stop condition and the auto-increment address is not automatically reset to 0x00.
