Internal Registers

The device is operated over the I2C bus with registers that contain configuration, status, and result information. All registers are 16 bits long.

There are four main registers: result, configuration, low-limit, and high-limit. There are also two ID registers: manufacturer ID and device ID. Table 6 lists these registers.
