The table below provides a list of the registers for advanced configuration functions
available in the device and the corresponding addresses.
Advanced configuration registers are accessible when FUNC_CFG_EN is set to '1' in
CTRL2_A (21h). Once enabled, access to the advanced configuration registers can be
disabled by setting the FUNC_CFG_EN bit to ‘1’ in CTRL2_A (3Fh).

Registers marked as Reserved must not be changed. Writing to those registers may cause
permanent damage to the device.
The content of the registers that are loaded at boot should not be changed. They contain the
factory calibration values. Their content is automatically restored when the device is
powered up.
