Modes of Operation

Figure 9. FXOS8700CQ power mode transition diagram

All register contents are preserved when transitioning from Active to Standby mode. Some registers are reset when transitioning

from Standby to Active. These are all noted in the device memory map register table. The Sleep and Wake modes are active

modes. For more information on how to use the Sleep and Wake modes and configuring the device to transition between them,

please refer to Section 7, “Embedded Functionality” or Freescale application note AN4074.
