Reserved. Read return 0x00.
1. Register contents are preserved when transition from ACTIVE to STANDBY mode occurs.
2. Register contents are reset when transition from STANDBY to ACTIVE mode occurs.
3. Modification of this register’s contents can only occur when device is STANDBY mode except CTRL_REG1 ACTIVE bit and CTRL_REG2
RST bit.
Note : Auto-increment addresses which are not a simple increment are highlighted in bold . The auto-increment addressing is only enabled when
device registers are read using I 2 C burst read mode. Therefore the internal storage of the auto-increment address is cleared whenever a
stop-bit is detected.
