Notes:
(1) Warning: Do not write to unpublished or reserved register locations.
(2) * Registers with checksum protection.
** When setting the AVG_MODE bit (AVG_MODE = ‘1’) in the Config2 register, the device will
use the Line-cycle Synchronized Averaging mode and the CycleCount register will be includ-
ed in the checksum. Otherwise the SampleCount register will be included.
(3) Registers that can be set to write protect from DSP and/or HOST.
