The device is controlled and monitored by registers accessed through the I²C interface. These

registers provide device control functions and can be read to determine the device status and acquire

device data.

The register set is summarized below in Figure 44. The values of all registers and fields that are listed

as reserved, or are not listed, must not be changed. Two-byte fields are always latched with the low

byte, followed by the high byte. The “Name” column illustrates the purpose of each register by

highlighting the function associated with each bit. The bits are shown from MSB (D7) to LSB (D0). The

grey fields are reserved, and their values must not be changed.
