8.5.1.7 Auto-Increment Feature

The auto-increment feature allows writing or reading several consecutive registers within one transmission. For example, when an 8-bit word is sent to the device, the internal address index counter is incremented by 1, and the next register is written. The auto-increment feature is enabled by default and can be disabled by setting the Auto_Incr_EN bit = 0 in the DEVICE_CONFIG1 register. The auto-increment feature is applied for the full register address from 0h to FFh.
