I 2 C Device Read/Write Operations
All device read/write operations are memory mapped. Device actions e.g. “Start Conversions” are controlled by writing to the
appropriate memory address location.
?
?
For I 2 C the 7-bit Device Address (from Table 2) has a read/write toggle bit, where the least significant bit is ‘1’ for read
operations or ‘0’ for write operations. The Device Address is 0xC0 for a Write and the Device Address is 0xC1 for a Read .
The most significant bit in the Command tables below is not used and is don't care (X). In examples given it’s set to ‘0’.
Refer to Sensor I 2 C Setup and FAQ Application Note AN4481 for more information on I 2 C communication between the sensor
and host controller.

X = Don’t care
1 = The command byte needs to be paired with a 0x00 as part of the I 2 C exchange to complete the passing of Start Conversions.
